Finite simple permutation groups acting with fixity 4
Barbara Baumeister, Paula Hähndel, Kay Magaard +2
Motivated by the theory of Riemann surfaces and specifically the significance of Weierstrass points, we classify all finite simple groups that have a faithful transitive action wit…
Transitive permutation groups with trivial four point stabilizers
Kay Magaard, Rebecca Waldecker
In this paper we analyze the structure of transitive permutation groups that have trivial four point stabilizers, but some nontrivial three point stabilizer. In particular we give…
Primitive Monodromy Groups of Genus at most Two
Daniel Frohardt, Robert Guralnick, Kay Magaard
We show that if the action of a classical group on a set of -spaces of its natural module is of genus at most two, then .
Image of the braid groups inside the finite Iwahori-Hecke algebras
Olivier Brunat, Kay Magaard, Ivan Marin
We determine the image of the braid groups inside the Iwahori-Hecke algebras of type A, when defined over a finite field, in the semisimple case, and for suitably large (but contro…
Imprimitive irreducible modules for finite quasisimple groups
Gerhard Hiss, William J. Husen, Kay Magaard
Motivated by the maximal subgroup problem of the finite classical groups we begin the classification of imprimitive irreducible modules of finite quasisimple groups. We obtain our…
Algorithmic construction of Chevalley bases
Kay Magaard, Robert Wilson
We present a new algorithm for constructing a Chevalley basis for any Chevalley Lie algebra over a finite field. This is a necessary component for some constructive recognition alg…
