Title: Longer nilpotent series
 
Speaker: James B. Wilson (Colorado State University, USA)
 
Abstract: We introduce new characteristic nilpotent series for
groups by refining the usual series of Fitting-Hall, Higman,
Jennings, Lazard and others. These refinements can increase
the length of the series by an arbitrary amount; so, they
constrain the possible automorphisms of a group considerably
and make many low class groups resemble groups of much larger
class. Also, these longer series maintain a correspondence
with graded Lie rings. The refinements rely on Jordan and Lie
algebras, commutative and non-commutative rings, and *-rings,
but despite their unusual origins, each refinement can be
computed by solving systems of linear equations and so they
are practical tools. The talk will assume only modest
background for groups and rings and include examples and open
questions.
 
You are cordially invited!
