Local freeness conjecture for pluricanonical direct images of weakly semistable morphisms
Local freeness conjecture for pluricanonical direct images of weakly semistable morphisms
Let be a weakly semistable morphism with connected fibers. Here weak semistability includes the toroidal, equidimensional, reduced-fiber, and smooth-base conditions stated in the source.
Local freeness conjecture for weakly semistable morphisms. The sheaf
is locally free for every .
This is proposed as a conjecture for weakly semistable morphisms and concerns the local behavior of relative pluricanonical direct images; the source does not state whether it has been resolved.
