DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MITNT/80/">R
 elative Langlands and Endoscopy</a>\nby Spencer Leslie (Boston College) as
  part of MIT number theory seminar\n\nLecture held in Room 2-449 in the Si
 mons Building (building 2).\n\nAbstract\nIn this talk\, I will discuss the
  motivation for a theory of endoscopy in the context of the relative Langl
 ands program. I then outline the construction of endoscopic varieties\, wh
 ich are spherical varieties of an associated endoscopic group. The constru
 ction works for most hyperspherical varieties induced from symmetric varie
 ties\, and relies on new rationality results for such varieties. We highli
 ght the role played by the dual Hamiltonian variety associated to a symmet
 ric variety a la Ben-Zvi\, Sakellaridis\, and Venkatesh.\n
