DESCRIPTION:Title: <a href="https://researchseminars.org/talk/WiSe/14/">Wh
 at is a Hecke algebra?</a>\nby Anna Romanov (University of Sydney) as part
  of What is ...? Seminar\n\n\nAbstract\nIf you hang around representation 
 theory circles\, you have probably heard a definition of a Hecke algebra. 
 (For example\, if you attended Anna Puskas’s WiSe talk last June.) If yo
 u hang around representation theory circles a lot\, you have probably hear
 d several definitions of a Hecke algebra. If you are like me\, you may hav
 e found this confusing. In this talk\, we will explore a few definitions o
 f Hecke algebras. I will try to explain why they arise naturally in the re
 presentation theory of groups\, and how the different definitions are rela
 ted. We’ll also take a detour into Gelfand pairs\, and explain how these
  fit into the story.\n
