DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MITLie/17/">
 Elliptic stable envelopes and 3-dimensional mirror symmetry</a>\nby Yakov 
 Kononov (Columbia University) as part of MIT Lie groups seminar\n\nLecture
  held in 2-142.\n\nAbstract\nThe action of quantum groups on the K-theory 
 of Nakajima varieties takes the simplest form in the stable bases\, invent
 ed by D.Maulik and A.Okounkov\, and in their most advanced (elliptic) vers
 ion by M.Aganagic and A.Okounkov. In collaboration with A.Smirnov we disco
 vered and proved the factorization property of elliptic stable envelopes. 
 As a consequence\, we proved the conjectures of E.Gorsky and A.Negut. Also
  it gives a new interesting description of the operators of quantum differ
 ence equations\, shift operators and other quantities in enumerative geome
 try. The talk is based on joint works with A.Smirnov.\n
