Dp-minimal profinite groups and valuations on the integers
Tim Clausen
We study dp-minimal infinite profinite groups that are equipped with a uniformly definable fundamental system of open subgroups. We show that these groups have an open subgroup …

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…

Some model theory of profinite groups
Tim Clausen, Katrin Tent
We give some background on uniform pro-p groups and the model theory of profinite NIP groups.
