Rigid Clemens–Schmidt conjecture for limiting Frobenius structures
Rigid Clemens–Schmidt conjecture for limiting Frobenius structures
Let be a morphism of varieties over with a good lift around . Let be the limiting Frobenius structure at in dimension , and define
Let be obtained by pulling back along . Rigid Clemens–Schmidt conjecture. The morphism extends to a semistable degeneration with degenerate fibre and, for every such extension, there exists a covariant rigid homology functor on semistable -varieties, vanishing outside , for which an exact sequence of -isocrystals contains
This is the rigid-cohomological analogue of the Clemens–Schmidt sequence for complex semistable degenerations and would give the limiting Frobenius structure the predicted geometric meaning.
