Conjugacy in Finite Classical Groups

Giovanni De Franceschi currently works as a software developer in Verona. He completed a PhD in mathematics at the University of Auckland in 2018; some of this work formed part of his PhD thesis. Martin W. Liebeck has been a professor at Imperial College London since 1991, and was Head of Pure Mathematics there between 1997 and 2024. He has published about 170 articles and books on finite and algebraic groups, representation theory, probabilistic group theory, and applications of these topics to areas such as model theory in logic, Markov theory in probability, combinatorics, and the design of algorithms in computational algebra. Liebeck is a Fellow of the American Mathematical Society, and was the recipient of the London Mathematical Society’s Polya Prize in 2020.Eamonn A. O'Brien is a professor at the University of Auckland since 2006. His research interests are in group theory and computational algebra, with a particular focus on the development and implementation of effective algorithms and their application to solving related challenging problems. He has published about 100 research papers and is a coauthor of the "Handbook of Computational Group Theory." Many of his research outputs are incorporated into the leading computational algebra systems GAP and Magma. Elected a Fellow of the Royal Society of New Zealand in 2009 and awarded its 2020 Hector Medal, he is a recipient of a 2024 Humboldt Foundation Research Award.
