Orbit decidability and the conjugacy problem for some extensions of groups

O. Bogopolski, A. Martino, E. Ventura

Given a short exact sequence of groups with certain conditions, $1 \to F \to G \to H \to 1$ , we prove that $G$ has solvable conjugacy problem if and only if the corresponding action su…

On the integral cohomology of wreath products

Ian J Leary

Under mild conditions on the space X, we describe the additive structure of the integral cohomology of the space $X^{p} \times_{C_{p}} E C_{p}$ in terms of the cohomology of X. We give wea…

On universally stable elements

I. J. Leary, B. Schuster, N. Yagita

We show that certain subrings of the cohomology of a finite p-group P may be realised as the images of restriction from suitable virtually free groups. We deduce that the cohomolog…

Exactness of free and amenable groups by the construction of Ozawa kernels

Sarah Campbell

Using properties of their Cayley graphs, specific examples of Ozawa kernels are constructed for both free and amenable groups, thus showing that these groups satisfy Property O. It…

A description of auto-fixed subgroups in a free group

A. Martino, E. Ventura

Let $F$ be a finitely generated free group. By using Bestvina-Handel theory, as well as some further improvements, the eigengroups of a given automorphism of $F$ (and its fixed sub…

Automorphism groups of Riemann surfaces of genus p+1, where p is prime

M. Belolipetsky, G. A. Jones

We show that if $S$ is a compact Riemann surface of genus $g = p + 1$ , where $p$ is prime, with a group of automorphisms $G$ such that $∣ G ∣ \geq λ (g - 1)$ for some real number $λ > 6$ …
