Title: On the Bass conjecture.
Abstract:
In this talk we will discuss the Bass conjecture and explain why it can
be seen as the non-torsion-free analogue of the idempotent conjecture,
which is that the idempotents in the group ring of a torsion-free group
should be 0 or 1. We will discuss a class of groups arising from geometry
and for which the Bass conjecture holds, as well as some ingredients
needed for the proof. This is a joint work with J. Berrick and G. Mislin.
