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

open access: bronzeModel 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 ⩾ n .

Infinite Sharply Multiply Transitive Groups [PDF]

open access: yesJahresbericht Der Deutschen Mathematiker-vereinigung, 2016
The finite sharply 2-transitive groups were classified by Zassenhaus in the 1930’s. They essentially all look like the group of affine linear transformations x↦ax+b$x\mapsto ax+b$ for some field (or at least near-field) K$K$.

Group-subgroup subfactors revisited [PDF]

open access: yesQuantum Topology, 2023
For all Frobenius groups and a large class of finite multiply transitive permutation groups, we show that the corresponding group-subgroup subfactors are completely characterized by their principal graphs.

Block-transitive 3-(v, k, 1) designs on exceptional groups of Lie type [PDF]

open access: yesJournal of Algebraic Combinatorics, 2023
Let $\mathcal{D}$ be a non-trivial $G$-block-transitive $3$-$(v,k,1)$ design, where $T\leq G \leq \mathrm{Aut}(T)$ for some finite non-abelian simple group $T$.

Rank three innately transitive permutation groups and related 2-transitive groups [PDF]

open access: yesInnovations in Incidence Geometry Algebraic Topological and Combinatorial, 2022
The sets of primitive, quasiprimitive, and innately transitive permutation groups may each be regarded as the building blocks of finite transitive permutation groups, and are analogues of composition factors for abstract finite groups. This paper extends

A subexponential bound on the cardinality of abelian quotients in finite transitive groups [PDF]

open access: yesBulletin of the London Mathematical Society, 2020
We show that, for every transitive permutation group G of degree n⩾2 , the largest abelian quotient of G has cardinality at most 4n/log2n . This gives a positive answer to a 1989 outstanding question of László Kovács and Cheryl Praeger.

Kinematic self-similar locally rotationally symmetric models [PDF]

open access: yes, 1998
A brief summary of results on kinematic self-similarities in general relativity is given. Attention is focussed on locally rotationally symmetric models admitting kinematic self-similar vectors.

Hurwitz Monodromy and Full Number Fields [PDF]

open access: yes, 2014
We give conditions for the monodromy group of a Hurwitz space over the configuration space of branch points to be the full alternating or symmetric group on the degree.
