Siegel operators for holomorphic differential forms
Shouhei Ma
We give a geometric interpretation of the Siegel operators for holomorphic differential forms on Siegel modular varieties. This involves extension of the differential forms over a…

Corank spectral sequence for locally symmetric varieties
Shouhei Ma
We construct a new type of spectral sequences for the mixed Hodge structures on the cohomology of locally symmetric varieties. These spectral sequences converge to the edge compone…
