The cohomology of the braid group B_3 and of SL_2(Z) with coefficients in a geometric representation
Filippo Callegaro, Fred Cohen, Mario Salvetti
The purpose of this article is to describe the integral cohomology of the braid group B_3 and SL_2(Z) with local coefficients in a classical geometric representation given by symme…
