Eisenstein cocycles for GL(n) and values of L-functions in imaginary quadratic extensions

Number Theory 2020-01-23 v2

Abstract

We generalize Sczech's Eisenstein cocycle for GL(n)\mathrm{GL}(n) over totally real extensions of Q\mathbb{Q} to finite extensions of imaginary quadratic fields. By evaluating the cocycle on certain cycles, we parametrize complex values of Hecke L-functions previously considered by Colmez, giving a cohomological interpretation of his algebraicity result on special values of the L-functions.
