DESCRIPTION:Beck modules for a monoid\n\nGiven an object X of a category C\
 , a Beck module for X is an abelian group object in the slice category C/X
 . For a ring R\, it is a 2-sided R-module\; for a group G\, it is a right 
 G-module\; for a commutative ring R\, it is just an R-module\; for a Lie a
 lgebra L it is the usual notion of L-module. These depend on the ambient c
 ategory of course. But when a student in Paris named Leonard Guetta asked 
 me what was a Beck module for a monoid\, I assumed it was an ordinary modu
 le. But I was wrong. I will describe what it actually is. (This talk has b
 een rescheduled from the previous week.) (Notes for the talk are posted on
  the seminar webpage.)\n
