Orthogonal Stability
Gabriele Nebe, Richard Parker
A character (ordinary or modular) is called orthogonally stable if all non-degenerate quadratic forms fixed by representations with those constituents have the same determinant mod…
Equivariant quadratic forms in characteristic 2
Gabriele Nebe, Richard Parker
Let be a finite group and a finite field of characteristic . Denote by the -rank of the commutator factor group and by the number of self-dual simple $…
Polynomial-time proofs that groups are hyperbolic
Derek Holt, Stephen Linton, Max Neunhoeffer +3
It is undecidable in general whether a given finitely presented group is word hyperbolic. We use the concept of pregroups, introduced by Stallings, to define a new class of van Kam…
Computational Modular Character Theory
Gerhard Hiss, Christoph Jansen, Klaus Lux +1
This book describes some computational methods to deal with modular characters of finite groups. It is the theoretical background of the MOC system of the same authors. This system…
A parallel algorithm for Gaussian elimination over finite fields
Stephen Linton, Gabriele Nebe, Alice Niemeyer +2
In this paper we describe a parallel Gaussian elimination algorithm for matrices with entries in a finite field. Unlike previous approaches, our algorithm subdivides a very large i…
A method for building permutation representations of finitely presented groups
Gabriele Nebe, Richard Parker, Sarah Rees
We design an algorithm to find certain partial permutation representations of a finitely presented group (the bricks) that may be combined to a transitive permutation represent…
