DESCRIPTION:The speaker on October 8 is: Lewis Topley (Birmingham)\n\nTit
 le: Yangians and representations of the general linear Lie algebra in po
 sitive characteristic\n\nAbstract: In this talk I will discuss the repre
 sentation theory of the general linear Lie algebra over a field of posit
 ive characteristic. The irreducible representations factor through certa
 in quotients of the enveloping algebra\, known as reduced enveloping alg
 ebras. It turns out that these reduced enveloping algebras may be descri
 bed completely by examining a finite collection of such algebras\, label
 led by the conjugacy classes of nilpotent matrices of rank n. Premet has
  shown that each of these reduced enveloping algebras is actually Morita
  equivalent to an algebra known as a restricted finite W-algebra. The ma
 in result of this talk is a joint work with Simon Goodwin\, in which we 
 show that these restricted finite W-algebras can be described explicitly
  as certain subquotients of a Yangian.\n\nPlace: Frank Adams 1. \n\nTime
 : 2pm.\n\nThere will be tea and biscuits from 1:40pm. All are welcome to
  attend.\n
