Title: A Lefschetz Theorem for Crystalline Local Systems

Abstract: Carlos Simpson proved a strong Lefschetz theorem for complex polarized VHS via nonabelian Hodge theory. We give an arithmetic analogue using the p-adic nonabelian Hodge correspondence. This is joint work with R. Krishnamoorthy and J.B. Yang.
