SUMMARY: Cumulants and Stack-Sorting 
LOCATION:zoom
DESCRIPTION:<p><em>Abstract</em>: Cumulant sequences are numerical sequences that play 
 a fundamental role in noncommutative probability theory. West's stack-sorti
 ng map is a combinatorially-defined operator that acts on permutations. In 
 this talk, we will discuss how cumulants and stack-sorting, two topics from
  very disparate worlds, are actually very closely related. This unexpected 
 connection allows us to use tools from noncommutative probability theory to
  prove difficult, surprising, and (occasionally) weird facts about the stac
 k-sorting map. We will explore several applications of this method.</p>
