Arithmetic Study Group: Torsion homology of arithmetic lattices and K2 of imaginary fields

Presented by Vincent Emery, EPF Lausanne

11 March 2014 13:00 in CM219

I will present results that give upper bounds for the torsion in
homology of nonuniform arithmetic lattices, and explain how together
with recent results of Calegari-Venkatesh this can be used to obtain
upper bounds on K2 of the ring of integers of totally imaginary fields.
