DESCRIPTION:Pseudo-reductive groups are smooth connected linear algebraic 
 groups over a field k whose k-defined unipotent radical is trivial. If k i
 s perfect then all pseudo-reductive groups are reductive\, but if k is imp
 erfect (hence of characteristic p) then one gets a strictly larger collect
 ion of groups. They come up in a number of natural situations\, not least 
 when one wishes to say something about the simple representations of all s
 mooth connected linear algebraic groups. Recent work by Conrad-Gabber-Pras
 ad has made it possible to reduce the classification of the simple represe
 ntations of pseudo-reductive groups to the split reductive case. I’ll ex
 plain how. This is joint work with Mike Bate and Ben Martin.
