Cohomology of Finite and Affine Type Artin Groups over Abelian Representation

The classical theory of braids is deeply connected with the theory of reflection groups, and there are many relations between Artin groups and Coxeter groups. This book describes the cohomology for Artin groups of type A and B and for affine Artin groups.

A resume of several results and costructions on braid cohomology is provided

Original results with explicit cohomology descriptions are given

A useful bibliography on braid cohomology
