Some examples and results on integral p-adic Hodge filtrations
Shizhang Li (University of Michigan)
Abstract: Given a smooth proper scheme over a mixed characteristic DVR, we try to understand to what extent the special fiber knows the Hodge numbers of the generic fiber. I'll provide some examples as well as a theorem showing that in "good" situations some numbers defined purely using the special fiber actually give the Hodge numbers of the generic fiber. This naturally leads to consideration of Breuil-Kisin prismatic cohomology, and I'll describe an example which illustrates certain pathological behavior of Hodge-Tate and Hodge-de Rham spectral sequences in mixed characteristic situations.
