Interpolating coefficient systems and $p$-ordinary cohomology of arithmetic groups

Günter Harder[1]

(1) Bonn, Germany

We present an approach to Hida’s theory of $p$-adically interpolating the ordinary cohomology of arithmetic groups and we discuss some application of this approach to special values of $L$-functions.

Keywords: Cohomology of arithmetic groups
