Algebra seminar in Lincoln: talk by Dan Segal

Charlotte Scott Centre for Algebra

On 25th of April 2018, Professor Dan Segal (University of Oxford) visited the University of Lincoln and gave a talk at the Algebra seminar “On groups of finite upper rank”.

Abstract: The upper rank of a group is the supremum of the Prüfer ranks of its finite quotient groups. The upper p-rank, for a prime p, is defined analogously, using the Sylow p-subgroups of finite quotients. I’ll discuss to what extent the upper rank of a finitely generated group is controlled by its upper p-ranks.
