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