Compatibility of global and critical obstruction theories for local Quot schemes
Let be the smooth toric threefold, let be the affine chart associated with a torus fixed point, and let be the sheaf under consideration. Let be the global perfect obstruction theory on , and let
be the open immersion. Denote by the critical obstruction theory on the local Quot scheme.
Compatibility conjecture. The restriction agrees, as a symmetric perfect obstruction theory, with .
This would identify the global obstruction theory with the critical-locus obstruction theory on each local chart. The source notes that the general result is open, although the corresponding K-theory class comparison is known.
