Explicitly combing hedgehogs over fields of Stufe 4

Peter Müller

Let $K [x, y, z] = K [X, Y, Z] / (X^{2} + Y^{2} + Z^{2} - 1)$ be the coordinate ring of the algebraic unit sphere over a field $K$ . Umberto Zannier showed that there exists a matrix in $\operatorname{SL…

A note about Jordan's bound on the size of finite linear groups

Peter Müller

In 1878 Camille Jordan showed that every finite subgroup $G \leq GL_{n} (C)$ has an abelian normal subgroup $A$ such that $∣ G / A ∣$ is bounded in terms of $n$ , bu…

Transitive sets of derangements in primitive actions of PSL_2(q)

Peter Müller

Problem 8.75 of the Kourovka Notebook [10], attributed to John G. Thompson, asks the following: Suppose $G$ is a finite primitive permutation group on $Ω$ , and $α$ , $β$ are distinc…

Normal subgroups and permutation characters: a correction to a proof of Klingen

Peter Muller, Pablo Spiga

Let $G$ be a finite group. For subgroups $U$ and $V$ let $1_{U}^{G}$ and $1_{V}^{G}$ be the permutation characters for the action of $G$ on the right cosets of $U$ and $V$ , respectively. L…

A note about solvable and non-solvable finite groups of the same order type

Peter Müller

Two finite groups are said to have the same order type if for each positive integer $n$ both groups have the same number of elements of order $n$ . In 1987 John G. Thompson asked if…
