Many years ago Auslander noticed that, for an isolated Gorenstein singularity, there is a natural trace defined on homomorphisms between certain pairs of modules. A conjectural formula was given recently by Kapustin and Li, using physics heuristics. We will discuss Murfet's mathematical proof of the formula |
