Groups of finite Morley rank with a generically multiply transitive action on an abelian group

open access: yesModel theory, 2022
We investigate the configuration where a group of finite Morley rank acts definably and generically $m$-transitively on an elementary abelian $p$-group of Morley rank $n$, where $p$ is an odd prime, and $m\geqslant n$. We conclude that $m=n$, and the action is equivalent to the natural action of $\operatorname{GL}_n(F)$ on $F^n$ for some algebraically ...

Groups of finite Morley rank with a generically sharply multiply transitive action [PDF]

open access: yesJournal of Algebra, 2018
We prove that if $G$ is a group of finite Morley rank which acts definably and generically sharply $n$-transitively on a connected abelian group $V$ of Morley rank $n$ with no involutions, then there is an algebraically closed field $F$ of characteristic $\ne 2$ such that $V$ has a structure of a vector space of dimension $n$ over $F$ and $G$ acts on ...

Normal subgroups of finite multiply transitive permutation groups [PDF]

open access: yesNagoya Mathematical Journal, 1974
Wagner [5] and Ito [2] proved the following theorems respectively.THEOREM OF WAGNER. Let G be a triply transitive permutation group on a set Ω = {1,2, …, n}, and let n be odd and n > 4. If H is a normal subgroup (≠1) of G, then H is also triply transitive on Ω.

Conjugacy Classes of Involutions in the Group of Homeomorphisms of the Rational Numbers

open access: yes, 2001
Let X be the set of real rational numbers Q with the topology induced by the usual topology on R and let AutX be the set of functions f : X → X which are homeomorphisms with respect to this topology.
