DESCRIPTION:Speaker: Eric Yen-Yo Chen\nhosted by Tamas Hausel\nAbstract: Re
 lative Langlands duality\, as recently introduced by Ben-Zvi--Sakellaridis
 --Venkatesh\, posits that well known formulae in the theory of automorphic
  periods can be understood as a duality of Hamiltonian actions by Langland
 s dual groups. In the expository half of the talk\, I will introduce relat
 ive duality and its relation with fundamental concepts in the Langlands pr
 ogram: automorphic periods\, L-functions\, and functoriality. In the secon
 d half\, I will discuss joint work with Akshay Venkatesh in which we follo
 w this philosophy to understand the duality underlying integral representa
 tions of L-functions discovered by Garrett and Ginzburg more than 30 years
  ago. In doing so\, we describe a new numerical invariant of L-parameters\
 , generalising Langlands' notion of L-functions.
