+\section{From differentials to differential forms}
+
+In a formal sense, we may define differentials as the vector space of
+linear mappings from curves to the reals, that is, given a
+differential $df$ we may use it to map any curve, C $ \in \mathit{C}$
+to a real number simply by integrating:
+\[df:C \rightarrow R\]
+\[ x = \int_C{df}\]
+This suggests a generalization, since we know how to integrate over
+surfaces and volumes as well as curves. In higher dimensions we also
+have higher order multiple integrals. We now consider the integrands
+of arbitrary multiple integrals
+\[\int{f(x)}dl,\quad\int\int{f(x)}dS,\quad\int\int\int{f(x)}dV\]
+Much of their importance lies in the coordinate invariance of the
+resulting integrals.
+
+One of the important properties of integrands is that they can all be
+regarded as oriented. If we integrate a line integral along a curve
+from $A$ to $B$ we get a number, while if we integrate from $B$ to $A$
+we get minus the same number,
+\[\int_A^B{f(x)}dl= -\int_B^A{f(x)}dl\]
+We can also demand oriented surface integrals, so the surface integral
+\[\int\int{\bf A\cdot n}~dS\]
+changes sign if we reverse the direction of the normal to the surface.
+This normal can be thought of as the cross product of two basis
+vectors within the surface. If these basis vectors' cross product is
+taken in one order, {\bf n} has one sign. If the opposite order is
+taken then {\bf -n} results. Similarly, volume integrals change sign
+if we change from a right- or left-handed coordinate system.
+
+\subsection{The wedge product}
+
+We can build this alternating sign into our convention for writing
+differential forms by introducing a formal antisymmetric product,
+called the {\sl wedge} product, symbolized by $\wedge$, which is
+defined to give these differential elements the proper signs. Thus,
+surface integrals will be written as integrals over the products
+\[{\bf dx} \wedge {\bf dy},
+ {\bf dy} \wedge {\bf dz},
+ {\bf dz} \wedge {\bf dx}\]
+with the convention that $\wedge$ is antisymmetric:
+\[{\bf dx} \wedge {\bf dy} = -{\bf dy} \wedge {\bf dx}\]
+under the interchange of any two basis forms. This automatically gives
+the right orientation of the surface. Similarly, the volume element
+becomes
+\[{\bf V} = {\bf dx} \wedge {\bf dy} \wedge {\bf dz}\]
+which changes sign if any pair of the basis elements are switched.
+
+We can go further than this by formalizing the full integrand. For
+a line integral, the general form of the integrand is a linear
+combination of the basis differentials,
+\[{\bf A}_x{\bf dx} + {\bf A}_y{\bf dy} + {\bf A}_z{\bf dz}\]
+Notice that we simply add the different parts. Similary, a general
+surface integrand is
+\[{\bf A}_z {\bf dx \wedge dy} +
+ {\bf A}_y {\bf dz \wedge dx} +
+ {\bf A}_x {\bf dy \wedge dz }\]
+while the volume integrand is
+\[f(x)~{\bf dx \wedge dy \wedge dz}\]
+These objects are called {\sl differential forms}.
+
+Clearly, differential forms come in severaly types. Functions are
+called 0-forms, line elements 1-forms, surface elements 2-forms, and
+volume elements are called 3-forms. These are all the types that exist
+in 3-dimensions, but in more than three dimensions we can have
+$p$-forms with $p$ ranging from zero to the dimension, $d$, of the
+space. Since we can take arbitrary linear combinations of $p$-forms,
+they form a vector space, $\Lambda_p$.
+
+We can always wedge together any two forms. We assume this wedge
+product is associative, and obeys the usual distributive laws. The
+wedge product of a $p$-form with a $q$-form is a $(p+q)$-form.
+
+Notice that the antisymmetry is all we need to rearrange any
+combination of forms. In general, wedge products of even order forms
+with any other forms commute while wedge products of pairs of
+odd-order forms anticommute. In particular, functions (0-forms)
+commute with all $p$-forms. Using this, we may interchange the order
+of a line element and a surface area, for if
+\[{\bf l} = A~{\bf dx}\]
+\[{\bf S} = B~{\bf dy \wedge dz}\]
+then
+\[\begin{array}{rcl}
+{\bf l \wedge S}&=& (A~{\bf dx}) \wedge (B~{\bf dy \wedge dz})\\
+&=&A~{\bf dx} \wedge B~{\bf dy \wedge dz}\\
+&=&AB~{\bf dx \wedge dy \wedge dz}\\
+&=&-AB~{\bf dy \wedge dx \wedge dz}\\
+&=&AB~{\bf dy \wedge dz \wedge dx}\\
+&=&{\bf S \wedge l}
+\end{array}\]
+but the wedge product of two line elements changes sign, for if
+\[{\bf l}_1 = A~{\bf dx}\]
+\[{\bf l}_2 = B~{\bf dy} + C~{\bf dz}\]
+then
+\[\begin{array}{rcl}
+{\bf l}_1 \wedge {\bf l}_2&=&(A~{\bf dx}) \wedge(B~{\bf dy}+C~{\bf dz})\\
+&=&A~{\bf dx} \wedge B~{\bf dy} + A~{\bf dx} \wedge C~{\bf dz}\\
+&+&AB~{\bf dx \wedge dy} + AC~{\bf dx \wedge dz}\\
+&=&-AB~{\bf dy \wedge dx} - AC~{\bf dz \wedge dz}\\
+&=&-B~{\bf dy} \wedge A~{\bf dx} - C~{\bf dz} \wedge A~{\bf dx}\\
+&=&-{\bf l}_2 \wedge {\bf l}_1
+\end{array}\]
+For any odd-order form, $\omega$, we immediately have
+\[\omega \wedge\omega = -\omega \wedge\omega = 0\] In 3-dimensions there
+are no 4-forms because anything we try to construct must contain a
+repeated basis form. For example,
+\[\begin{array}{rcl}
+{\bf l} \wedge {\bf V}&=&(A~{\bf dx}) \wedge(B~{\bf dx \wedge dy \wedge dz})\\
+&=&AB~{\bf dx \wedge dx \wedge dy \wedge dz}\\
+&=&0
+\end{array}\]
+since ${\bf dx \wedge dx}=0$. The same occurs for anything we try. Of
+course, if we have more dimensions then there are more independent
+directions and we can find nonzero 4-forms. In general, in
+$d$-dimensions we can find $d$-forms, but no $(d+1)$-forms.
+
+Now suppose we want to change coordinates. How does an integrand change?
+Suppose Cartesian coordinates (x,y) in the plane are given as some
+functions of new coordinates (u,v). Then we already know that
+differentials change according to
+\[{\bf dx} = {\bf dx}(u,v) =
+ \frac{\partial x}{\partial u}{\bf du} +
+ \frac{\partial x}{\partial v}{\bf dv}\]
+and similarly for ${\bf dy}$, applying the usual rules for partial
+differentiation. Notice what happens when we use the wedge
+product to calculate the new area element:
+\[\begin{array}{rcl}
+{\bf dx} \wedge{\bf dy}&=&
+\displaystyle\left(\frac{\partial x}{\partial u}{\bf du}+
+ \frac{\partial x}{\partial v}{\bf dv}\right) \wedge
+\displaystyle\left(\frac{\partial y}{\partial u}{\bf du}+
+ \frac{\partial y}{\partial v}{\bf dv}\right)\\
+&&\\
+&=&\displaystyle\frac{\partial x}{\partial v}\frac{\partial y}{\partial u}
+ {\bf dv \wedge du} +
+ \displaystyle\frac{\partial x}{\partial u}\frac{\partial y}{\partial v}
+ {\bf du \wedge dv} \\
+&&\\
+&=&\left(
+\displaystyle\frac{\partial x}{\partial u}\frac{\partial y}{\partial v}-
+\displaystyle\frac{\partial x}{\partial v}\frac{\partial y}{\partial u}
+\right) {\bf du \wedge dv}\\
+&&\\
+&=&\mathit{J}~{\bf du \wedge dv}
+\end{array}\]
+where
+\[J=\textrm{det}\left(
+\begin{array}{rcl}
+\displaystyle\frac{\partial x}{\partial u} &
+\displaystyle\frac{\partial x}{\partial v}\\
+&\\
+\displaystyle\frac{\partial y}{\partial u} &
+\displaystyle\frac{\partial y}{\partial v}
+\end{array}
+\right)\]
+is the Jacobian of the coordinate transformation. This is exactly the
+way that an area element changes when we change coordinates. Notice
+the Jacobian coming out automatically. We couldn't ask for more -
+the wedge product not only gives us the right signs for oriented
+areas and volumes, but gives us the right transformation to new
+coordinates. Of course the volume change works, too.
+
+Under a coordinate transformation
+\[ x \rightarrow x(u,v,w)\]
+\[ y \rightarrow y(u,v,w)\]
+\[ z \rightarrow z(u,v,w)\]
+the new volume element is the full Jacobian times the new volume form,
+\[{\bf dx \wedge dy \wedge dz} = J(xyz;uvw)~{\bf du \wedge dv \wedge dw}\]
+
+So the wedge product successfully keesp track of $p$-dim volumes and
+their orientations in a coordinate invariant way. Now any time we have
+an integral, we can regard the integrand as being a differential form.
+But all of this can go much further. Recall our proof that 1-forms form
+a vector space. Thus, the differential, ${\bf dx}$ of $x(u,v)$ given
+above is just a gradient. It vanishes along surfaces where $x$ is
+constant, and the components of the vector
+\[\displaystyle\left(
+\frac{\partial x}{\partial u},\frac{\partial x}{\partial v}\right)
+\]
+point in a direction normal to those surfaces. So symbols like
+${\bf dx}$ or ${\bf du}$ contain directional information. Writing
+them with a boldface {\bf d} indicates this vector character. Thus,
+we write
+\[{\bf A} = A_i{\bf dx^i}\]
+
+Let
+\[f(x,y)=axy\]
+The vector with components
+\[\displaystyle\left(
+\frac{\partial f}{\partial u},\frac{\partial f}{\partial v}\right)
+\]
+is perpendicular to the surfaces of constant $f$.
+
+We have defined forms, have written down their formal properties, and have
+used those properties to write them in components. Then, we define the
+wedge product, which enables us to write $p$-dimensional integrands as
+$p$-forms in such a way that the orientation and coordinate transformation
+properties of the integrals emerges automatically.
+
+Though it is 1-forms, $A_i{\bf dx^i}$ that corresponding to vectors,
+we have defined a product of basis forms that we can generalize to
+more complicated objects. Many of these objects are already
+familiar. Consider the product of two 1-forms.
+\[\begin{array}{rcl}
+{\bf A} \wedge {\bf B}
+&=&A_i~{\bf dx}^i \wedge B_j~{\bf dx}^j\\
+&=&A_iB_j~{\bf dx}^i \wedge {\bf dx}^j\\
+&=&\displaystyle\frac{1}{2}
+A_iB_j~({\bf dx}^i \wedge {\bf dx}^j-{\bf dx}^j \wedge {\bf dx}^i)\\
+&&\\
+&=&\displaystyle\frac{1}{2}
+(A_iB_j~{\bf dx}^i \wedge {\bf dx}^j-A_iB_j~{\bf dx}^j \wedge {\bf dx}^i)\\
+&&\\
+&=&\displaystyle\frac{1}{2}
+(A_iB_j~{\bf dx}^i \wedge {\bf dx}^j-A_jB_i~{\bf dx}^i \wedge {\bf dx}^j)\\
+&&\\
+&=&\displaystyle\frac{1}{2}(A_iB_j-A_jB_i)~{\bf dx}^i \wedge {\bf dx}^j
+\end{array}\]
+The coefficients
+\[A_iB_j-A_jB_i\]
+are essentially the components of the cross product. We will see this in
+more detail below when we discuss the curl.
+
+\subsection{The exterior derivative}
+
+We may regard the differential of any function, say $f(x,y,z)$, as the
+1-form:
+\[\begin{array}{rcl}
+{\bf d}f&=&
+\displaystyle\frac{\partial f}{\partial x}{\bf d}x+
+\displaystyle\frac{\partial f}{\partial y}{\bf d}y+
+\displaystyle\frac{\partial f}{\partial z}{\bf d}z\\
+&&\\
+&=&\displaystyle\frac{\partial f}{\partial x^i}{\bf d}x^i
+\end{array}\]
+
+Since a fnction is a 0-form then we can imagine an operator {\bf d} that
+differentiates any 0-form to give a 1-form. In Cartesian coordinates,
+the coefficients of this 1-form are just the Cartesian components of the
+gradient.
+
+The operator {\bf d} is called the {\sl exterior derivative}, and we may
+apply it to any $p$-form to get a $(p+1)$-form. The extension is defined
+as follows. First consider a 1-form
+\[{\bf A}=A_i~{\bf dx}^i\]
+We define
+\[{\bf dA}={\bf d}A_i \wedge {\bf dx}^i\]
+Similarly, since an arbitrary $p$-form in $n$-dimensions may be written as
+\[\omega=A_{i_1,i_2,\cdots,i_p} \wedge {\bf dx}^{i_1} \wedge {\bf dx}^{i_2}
+\cdots \wedge {\bf dx}^{i_p}\]
+we define the exterior derivative of $\omega$ to be a $(p+1)$-form
+\[{\bf d}\omega=
+{\bf d}A_{i_1,i_2,\cdots,i_p} \wedge {\bf dx}^{i_1} \wedge {\bf dx}^{i_2}
+\cdots \wedge {\bf dx}^{i_p}\]
+
+Let's see what happens if we apply ${\bf d}$ twice to the Cartesian
+coordinate, $x$ regarded as a function of $x,y$ and $z$:
+\[\begin{array}{rcl}
+{\bf d}^2x&=&{\bf d}({\bf d}x)\\
+&=&{\bf d}(1{\bf d}x)\\
+&=&{\bf d}(1) \wedge{\bf d}x\\
+&=&0
+\end{array}\]
+since all derivatives of the constant function $f=1$ are zero. The
+same applies if we apply {\bf d} twice to {\sl any} function:
+\[\begin{array}{rcl}
+{\bf d}^2f &=&{\bf d}({\bf d}f)\\
+&=&\displaystyle{\bf d}
+\left(\frac{\partial f}{\partial x^i}{\bf d}x^i\right)\\
+&&\\
+&=&\displaystyle{\bf d}
+\left(\frac{\partial f}{\partial x^i} \wedge {\bf d}x^i\right)\\
+&&\\
+&=&\displaystyle\left(\frac{\partial^2 f}{\partial x^j\partial x^i}
+{\bf d}x^j\right) \wedge {\bf d}x^i\\
+&&\\
+&=&\displaystyle
+\frac{\partial^2 f}{\partial x^j\partial x^i}{\bf d}x^j \wedge{\bf d}x^i
+\end{array}\]
+By the same argument we used to get the components of the curl, we may
+write this as
+\[\begin{array}{rcl}
+{\bf d}^2f&=&\displaystyle\frac{1}{2}\left(
+\displaystyle\frac{\partial^2f}{\partial x^j\partial x^i}-
+\displaystyle\frac{\partial^2f}{\partial x^i\partial x^j}\right)
+{\bf d}x^j \wedge{\bf d}x^i\\
+&=&0
+\end{array}\]
+since partial derivatives commute.
+
+Poincar\'e Lemma: ${\bf d}^2\omega=0$ where $\omega$ is an arbitrary $p$-form.
+\index{Poincar\'e Lemma}
+
+Next, consider the effect on {\bf d} on an arbitrary 1-form. We have
+\[\begin{array}{rcl}
+{\bf dA}&=&{\bf d}(A_i{\bf d}x^i)\\
+&&\\
+&=&\displaystyle\left(\frac{\partial A_i}{\partial x^j}{\bf d}x^j\right)
+ \wedge{\bf d}x^i\\
+&&\\
+&=&\displaystyle\frac{1}{2}\left(
+\frac{\partial A_i}{\partial x^j}-\frac{\partial A_j}{\partial x^i}\right)
+{\bf d}x^j \wedge{\bf d}x^i
+\end{array}\]
+We have the components of the curl of the vector {\bf A}. We must be
+careful here, however, because these are the components of the curl
+only in Cartesian coordinates. Later we will see how these components
+relate to those in a general coordinate system. Also, recall that the
+components $A_i$ are distinct from the usual vector components $A^i$.
+These differences will be resolved when we give a detailed discussion
+of the metric. Ultimately, the action of {\bf d} on a 1-form gives us
+a coordinate invariant way to calculate the curl.
+
+Finally, suppose we have a 2-form expressed as
+\[{\bf S}=A_z~{\bf d}x \wedge {\bf d}y+A_y~{\bf d}z \wedge {\bf d}x+
+A_x~{\bf d}y \wedge {\bf d}z\]
+Then apply the exterior derivative gives
+\[\begin{array}{rcl}
+{\bf d}S&=&{\bf d}A_z \wedge{\bf d}x \wedge{\bf d}y+
+{\bf d}A_y \wedge{\bf d}z \wedge{\bf d}x+
+{\bf d}A_x \wedge{\bf d}y \wedge{\bf d}z\\
+&&\\
+&=&\displaystyle\frac{\partial A_z}{\partial z}{\bf d}z \wedge{\bf d}x
+ \wedge{\bf d}y+
+\displaystyle\frac{\partial A_y}{\partial y}{\bf d}y \wedge{\bf d}z
+ \wedge{\bf d}x+
+\displaystyle\frac{\partial A_x}{\partial x}{\bf d}x \wedge{\bf d}y
+\wedge{\bf d}z\\
+&&\\
+&=&\displaystyle\left(
+\frac{\partial A_z}{\partial z}+
+\frac{\partial A_y}{\partial y}+
+\frac{\partial A_x}{\partial x}\right)~{\bf d}x \wedge{\bf d}y \wedge{\bf d}z
+\end{array}\]
+so that the exterior derivative can also reproduce the divergence.
+
+\subsection{The Hodge dual}
+
+To truly have the curl we need a way to turn a 2-form into a vector, i.e.,
+a 1-form and a way to turn a 3-form into a 0-form. This leads us to
+introduce the Hodge dual
+\index{Hodge dual}, or star, operator $\star$.
+
+Notice that in 3-dim, both 1-forms and 2-forms have three independent
+components, while both 0- and 3-forms have one component. This suggests
+that we can define an invertible mapping between these pairs. In
+Cartesian coordinates, suppose we set
+\[\begin{array}{rcl}
+\star({\bf dx} \wedge {\bf dy})&=&{\bf dz}\\
+\star({\bf dy} \wedge {\bf dz})&=&{\bf dx}\\
+\star({\bf dz} \wedge {\bf dx})&=&{\bf dy}\\
+\star({\bf dx} \wedge {\bf dy} \wedge {\bf dz})&=&1
+\end{array}\]
+and further require that the star be its own inverse
+\[\star\star = 1\]
+With these rules we can find the Hodge dual of any form in 3-dim.
+
+The dual of the general 1-form
+\[{\bf A} = A_i{\bf dx}^i\]
+is the 2-form
+\[S=A_z~{\bf dx} \wedge {\bf dy} + A_y~{\bf dz} \wedge {\bf dx} +
+A_x~{\bf dy} \wedge {\bf dz}\]
+
+For an arbitrary (Cartesian) 1-form
+\[{\bf A} = A_i{\bf dx}^i\]
+that
+\[\star{\bf d}\star{\bf A} = div {\bf A}\]
+
+The curl of {\bf A}
+\[curl({\bf A}) =
+\displaystyle\left(
+\frac{\partial A_y}{\partial z}-
+\frac{\partial A_z}{\partial y}\right){\bf dx}+
+\displaystyle\left(
+\frac{\partial A_z}{\partial x}-
+\frac{\partial A_x}{\partial z}\right){\bf dy}
+\displaystyle\left(\frac{\partial A_x}{\partial y}-
+\frac{\partial A_y}{\partial x}\right){\bf dz}\]
+
+Three operations - the wedge product $\wedge$, the exterior derivative
+{\bf d}, and the Hodge dual $\star$ - together encompass the usual dot
+and cross products as well as the divergence, curl and gradient. In fact,
+they do much more - they extend all of these operations to arbitrary
+coordinates and arbitrary numbers of dimensions. To explore these
+generalizations, we must first explore properties of the metric and
+look at coordinate transformations. This will allow us to define the
+Hodge dula in arbitrary coordinates.
