DESCRIPTION:Speakers: Ben Davison (University of Edinburgh)\n\nA partition
  of a positive integer n can be visualised as a Young diagram: a configura
 tion of n 2d boxes lying in the corner of the page.  The count of partiti
 ons of natural numbers are encoded in Euler's partition function\; this is
  the formal power series in t\, having as its t^n coefficient the number o
 f partitions of n.  As well as having an elegant infinite product present
 ation\, this partition function is related to the cohomology of Hilb_n(C^2
 ).  This is the space of colength n ideals in the polynomial algebra in t
 wo generators\, which is an important module in geometric representation t
 heory.\n\nhttps://math-events.uni-bonn.de/event/428/
