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, , we prove that has solvable conjugacy problem if and only if the corresponding action su…

Nonvanishing of algebraic entropy for geometrically finite groups of isometries of Hadamard manifolds
Roger C. Alperin, Guennady A. Noskov
We prove that any geometrically finite (nonelementary) group of isometries of a pinched Hadamard manifold has uniform exponential growth.

On the palindromic and primitive widths of a free group
Valery Bardakov, Vladimir Shpilrain, Vladimir Tolstykh
Let G be a group and S a subset of G that generates G. For each x in G define the length l_S(x) of x relative to S to be the minimal k such that x is a product of k elements of S.…
