Graduate Algebra and Representation Theory Seminar

Extended Affine Lie Algebras and Their Root Systems

Jason Saied, Rutgers University

Location:  Hill 525
Date & time: Monday, 04 December 2017 at 1:00PM - 2:00PM

Abstract: We will give definitions of extended affine root systems (EARS) and extended affine Lie algebras (EALAs). We will then use the notion of a semilattice in order to give constructions of all EARS. We will construct examples of EALAs and study whether every EARS arises as the root system of some EALA.
