| Nov 5 at 1:28 | comment | added | b0bgary | OK thankyou, I had been reading about the Gribov obstruction just before this. Suppose then that I'm considering a boundary of some finite region in a slice of $\mathbb{R}^4$. I only care about the value of $A$ on this closed curve, rather than all of $\mathbb{R}^4$. I understand that I can't have a global section, but what can I say about $A$ in this case? Is there a well-defined splitting on this submanifold? | |
