The Burnside problem for odd exponents

Agatha Atkarskaya, Eliyahu Rips, Katrin Tent

We show that the free Burnside groups are infinite for and odd , the best currently known lower bound for the exponent. The proof uses iterated small…

Simple sharply 2-transitive groups

Simon André, Katrin Tent

We construct simple sharply 2-transitive groups. Our result answers an open question of Peter Neumann. In fact, we prove that every sharply 2-transitive group of characteristic 0 e…

Mock hyperbolic reflection spaces and Frobenius groups of finite Morley rank

Tim Clausen, Katrin Tent

We define the notion of mock hyperbolic reflection spaces and use it to study Frobenius groups, in particular in the context of groups of finite Morley rank including the so-called…

Defining R and G(R)

Dan Segal, Katrin Tent

We show that for Chevalley groups G(R) of rank at least 2 over a ring R the root subgroups are essentially (nearly always) the double centralizers of corresponding root elements. I…

On the geometry of sharply 2-transitive groups

Tim Clausen, Katrin Tent

We show that the geometry associated to certain non-split sharply 2-transitive groups does not contain a proper projective plane. For a sharply 2-transitive group of finite Morley…

Simplicity of the automorphism groups of order and tournament expansions of homogeneous structures

Filippo Calderoni, Aleksandra Kwiatkowska, Katrin Tent

We define the notions of a free fusion of structures and a weakly stationary independence relation. We apply these notions to prove simplicity for the automorphism groups of order…
