THE FIRST OF THESE TALKS WAS ALREADY ANNOUNCED ON 
TECHMATH. PLEASE NOTE THAT ITS TIME HAS NOW BEEN
MOVED 30 MINUTES EARLIER.
 
There will be two talks in the seminar this week, 
so we will start at 10:00 and not at 10:30.  
 
Bar-Ilan Algebra Seminar
=========================================
 
Date: Wednesday, 14 Iyar 5771 // May 18, 2011
Place: Third floor seminar room, Mathematics building
 

((First Talk
10:00  (joint with CGC Colloquium)
Speaker:  Prof. Daniel Lenz (Friedrich-Schiller-Universitaet Jena)
Title:  Order based constructions of groupoids from inverse semigroups
SEE SEPARATE ANNOUNCEMENT WITH ABSTRACT.))


Second Talk 

Speaker: David Guiraud (Universite Paris 7, visiting Bar-Ilan)
Title:   On semisimple l-modular Bernstein blocks of a p-adic 
         general linear group
 

Abstract: 

Let G_n = GL_n(F), where F is a local non-archimedean field with
residue characteristic p. We are concerned with the Bernstein
decomposition into blocks of the representation category of G_n
over an algebraically closed field of characteristic l \neq p.
 In level zero, we construct a replacement for the Iwahori-Hecke
algebras, which gives rise to a description of the G_n-blocks
associated to semisimple supercuspidal pairs in terms of
G_m-blocks associated to simple supercuspidal pairs (with m< n),
paralleling the approach of Bushnell and Kutzko in the complex
setting.
