Date : Thursday 13 November Time : 3pm Room : Carslaw 173 Speaker : Derek Holt (Warwick) Title : Computing in finite matrix groups We review the extent to which the Composition Tree based methods of Baarnhielm, Leedham-Green, O’Brien et al can be used to carry out structural computations in large matrix groups over finite field without resort to methods based on bases and strong generating sets. We concentrate particularly on the computation of element centralisers, subgroup normalisers, conjugacy classes, and (work in progress) character tables.
