Mustață–Popa's local cohomological vanishing conjecture
Suppose is embedded in a smooth variety of dimension . Choose a log resolution
of the pair that is an isomorphism away from , and let
Thus is a simple normal crossings divisor on . Mustață–Popa's conjecture. If , then
The conjecture relates depth of the structure sheaf to vanishing in the Hodge filtration on local cohomology. The supplied source does not state whether it has been resolved, so its status is recorded as open here.
