Speaker: Eamonn O’Brien (Auckland) Title: Determination of p-groups and nilpotent Lie rings Time & Place: 3:05pm-4pm, Thursday 17 May, Carslaw 535 Abstract: I will report on recent work on the determination of p-groups and associated nilpotent Lie rings, focusing on those of order dividing p^7 for arbitrary primes p. In particular I will review the basic algorithm used and outline the use of the Baker-Campbell-Hausdorff formula to relate presentations for the ring and p-group.
