May I ask this: my main motivating example (which I probably should include in the question) was a passage from "Loop spaces, characteristic classes and geometric quantization" by Brylinski, where he proposes to interpret Dirac's magnetic fields with a singularity at the origin by line bundles on $\mathbb R^3\setminus\{0\}$. I was wondering what happens if one tries to extend such bundle to the whole $\mathbb R^3$ - seemingly certain cohomology class serves as an obstruction for that. So, what is this? Some sheaf on $\mathbb R^3$ or..? | |
