Stokes' Theorem on a punctured surface

155 Views Asked by At

Say we consider a punctured surface. For instance, $D^2 \setminus \{0\}$. We consider a vector field on this surface that is divergent at $0$. It could be proportional to $v(r) \sim\frac{1}{|r|^n}$. Is there a way to still apply Stokes' Theorem here when we want to calculate the flux of the curl of this vector field through the surface? I have been looking for an additional contribution coming from the pole but without any luck. Any help would be much appreciated! As would any literature on the subject.
