It doesn't make sense to speak of a path integral over a surface. A path or curve is by definition one-dimensional; a surface is by definition two-dimensional. Michael Hardy 01:24 Mar 21, 2003 (UTC)
- indeed, must we still use the \oint symbol then?
- yes, the \oint symbol is still appropriate. It's not just notation for one-dimensional closed-paths, it's also used for the integral taken over any closed manifold, a closed path is just the one-dimensional case, here, it means a closed 2-mainfold, or surface. Revolver
Differential Form
Shouldn't we include it in differential form too? I am too afraid to make mistakes myself to do it.
Partial form
<math>\nabla \cdot \mathbf{D} = \rho <math>
<math> \nabla \cdot <math> is the divergence
D is the electric displacement field (in units of C/m2).
ρ is the free electric charge density (in units of C/m3), not including dipole charges bound in a material
