Cautis–Logvinenko conjecture for the three-dimensional McKay correspondence
Let be a finite subgroup, let be the -Hilbert scheme, and let
be the inverse of the Bridgeland–King–Reid derived equivalence. For a representation of , write for the -equivariant coherent sheaf supported at the origin. Cautis–Logvinenko conjecture. For each nontrivial irreducible representation of , the object is a pure sheaf on . More precisely, there is a unique depending on such that
This predicts a geometric realization of the three-dimensional McKay correspondence through the supports of the images of irreducible representations. The source does not state whether the conjecture has been resolved.
