Cohomology of quasi-abelianized braid groups
speaker: Filippo Callegaro (Università di Pisa)abstract: We study the rational cohomology of the quotient of (generalized) braid groups by the commutator subgroup of the pure braid groups. We provide a combinatorial description of it using isomorphism classes of certain families of graphs. Several properties like Poincaré dualities and stabilization appear. This is a joint work with Ivan Marin.
