Abstract: In a joint work with Binyong Sun, we formulate a construction of p-adic measures attached to cohomological automorphic representations with ordinary refinements, using a relative version of completed cohomology. In the first talk we will explain the construction and examples such as the unitary GGP case, and also the calculation of modifying factors at p. In the second talk we will explain some details in the proof for the p-adic interpolation and p-adic integration.
