Pure Maths Colloquium: p-adic automorphic forms
2 March 2009 16:15 in CM221
In the talk, I'll recall how the space of complex valued automorphic forms can be used to calculate the complex valued cohomology of an arithmetic group. I'll then describe a natural space of "p-adic automorphic forms", which plays the same role in calculating the p-adic valued cohomology. I'll discuss some consequences of the theory.
