WebThe set of all di erential k-forms on a manifold Mat pis a vector space denoted k p (M). The set of all di erential k-forms on a manifold Mis a vec-tor space denoted k(M). So, a charge density is a 3-form, i.e., an element of 3(M). The space of all forms is denoted as (M) (Nakahara, [7] 1990; Frankel, [2] 1997). 2

After a line, a circle is the simplest example of a topological manifold. Topology ignores bending, so a small piece of a circle is treated the same as a small piece of a line. Considering, for instance, the top part of the unit circle, x + y = 1, where the y-coordinate is positive (indicated by the yellow arc in Figure 1). Any point of this arc can be uniquely described by its x-coordinate. So, projection o…
