==== abstract ====
The cohomology groups of arithmetic groups can, in principle, be computed explicitely. On the other hand we have some speculative ideas about the connection between the structure of these cohomology groups and the arithmetic properties of special values of L-functions. This allows us to make some interesting numerical experiments.
