On the model theory of open generalized polygons
Anna-Maria Ammer, Katrin Tent
We show that for any the theory of open generalized -gons is complete, decidable and strictly stable, yielding a new class of examples in the zoo of stable theories.
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…
