Abstract:
Let N_g denote a genus-g non-orientable closed surface, and let I(N_g) the subgroup of the mapping class group of N_g consisting of elements acting trivially on the integral first homology group of N_g. We call I(N_g) the Torelli group of N_g. In this talk, we will explain about a normally generating set for I(N_g). This is a joint work with Susumu Hirose from Tokyo University of Science.
