Boundary cohomology of wellpositioned subschemes of integral models of Shimura varieties
Boundary cohomology of wellpositioned subschemes of integral models of Shimura varieties

I will first review what we know about the toroidal and minimal compactifications of Shimura varieties and their integral models, and the wellpositioned subschemes of these integral models. Then I will explain some padic analogues of Harris and Zucker's work on the boundary cohomology of Shimura varieties and of wellpositioned subschemes of their integral models (when defined). (Based on thesis works of Peihang Wu and Shengkai Mao, and on joint work with David Sherman on padic log RiemannHilbert functors in the ideally log smooth case.)
