Cohomology of Fuchsian Groups and Non-Euclidean Crystallographic Groups
Abstract
For each geometrically finite 2-dimensional non-Euclidean crystallographic group (NEC group), we compute the cohomology groups. In the case where the group is a Fuchsian group, we also determine the ring structure of the cohomology.
