Abstract
I will give an overview of arithmetic properties of l-adic cohomology of algebraic varieties and rigid spaces over p-adic fields. A special focus will be given to integrality and p-adic valuations of Frobenius eigenvalues, with applications to weights and quasi-unipotence. This talk is partly based on joint work with Qing Lu.
