The integral cohomology of the group of loops
Craig A Jensen, Jon McCammond, John Meier
Let PSigma_n denote the group that can be thought of either as the group of motions of the trivial n-component link or the group of symmetric automorphisms of a free group of rank…
The center of some braid groups and the Farrell cohomology of certain pure mapping class groups
Yu Qing Chen, Henry H. Glover, Craig A. Jensen
In this paper we first show that many braid groups of low genus surfaces have their centers as direct factors. We then give a description of centralizers and normalizers of prime o…
The Euler characteristic of the Whitehead automorphism group of a free product
Craig Jensen, Jon McCammond, John Meier
A combinatorial summation identity over the lattice of labelled hypertrees is established that allows one to gain concrete information on the Euler characteristics of various autom…
The cohomology of right angled Artin groups with group ring coefficients
Craig Jensen, John Meier
We give an explicit formula for the cohomology of a right angled Artin group with group ring coefficients in terms of the cohomology of its defining flag complex.
Automorphisms of free groups with boundaries
Craig A. Jensen, Nathalie Wahl
The automorphisms of free groups with boundaries form a family of groups A_{n,k} closely related to mapping class groups, with the standard automorphisms of free groups as A_{n,0}…
On automorphism groups of free products of finite groups, I: Proper Actions
Yuqing Chen, Henry Glover, Craig Jensen
If is a free product of finite groups, let denote all (necessarily symmetric) automorphisms of that do not permute factors in the free product. We show that a M…
