Finite permutation groups that act 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 prove general structure results about finite groups that have a faithful tra…
Corrigendum to "Transitive permutation groups with trivial four point stabilizers"
Paula Hähndel, Christoph Möller, Rebecca Waldecker
This article revisits earlier work by the last author together with Kay Magaard. We correct mistakes in results about the Sylow 2- and 3-structure of groups that act with fixity 3…
Finite soluble groups that act with fixity 2 or 3
Paula Hähndel, Christoph Möller, Rebecca Waldecker
In this article we prove results about finite soluble groups that act with fixity 2 or 3.
Corrigendum and addendum to "Transitive permutation groups where nontrivial elements have at most two fixed points"
Paula Hähndel, Rebecca Waldecker
This article revisits earlier work by the second author together with Kay Magaard. We correct several little results and we briefly discuss why, fortunately, the errors hardly affe…
