welcome

Welcome to the webpage of our research group in computational group theory, algebraic design theory, and applications. This group was established at NUI Galway in 2008, and receives financial support from Science Foundation Ireland as well as other sources.

Scope

The group conducts research in two main domains.

Computational Group Theory (CGT)
Our purpose is to establish a new area of CGT: computing with matrix groups over infinite fields. We are developing special techniques for the efficient handling of linear groups over infinite fields by computer, and are using those techniques to answer a number of vital computational questions. A primary objective is the development of software that enables practical computing in this class of groups.

Algebraic Design Theory
A separate area of our research combines computational algebra and combinatorial design theory, and deals with problems arising in a new meta-theory covering all known types of pairwise combinatorial designs. These problems include deriving computational approaches to solving the 'norm equation' over group rings; determining the structure of an ideal in a certain infinite associative ring given a presentation of that ring; and calculating the automorphism group of a design and its regular subgroups. The ideal question is closely related to the problem of proving the famous Hadamard Conjecture.
