Outer automorphisms of free Burnside groups

Rémi Coulon[1]

(1) Vanderbilt University, Nashville, USA

In this paper, we study some properties of the outer automorphism group of free Burnside groups of large odd exponent. In particular, we prove that it contains free and free abelian subgroups.

Keywords: Geometric group theory, periodic groups, automorphism groups, hyperbolic geometry, small cancellation theory
