DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NT-UBC/6/">T
 owards a notion of mesoscopy</a>\nby Tian An Wong (U of Michigan) as part 
 of UBC Number theory seminar\n\nLecture held in ESB4133.\n\nAbstract\nWith
 in the Langlands program\, the theory of endoscopy concerns the transfer\n
 of distributions between a reductive group $G$ and $G'$\, an endoscopic\ng
 roup of $G$. At the heart of Langlands' original study on Beyond Endoscopy
 \nis the notion of stable transfer between groups $G$ and $G'$\, where $G'
 $ is\nno longer required to be an endoscopic group. Arthur referred to the
 se as\n'beyond endoscopic groups\,' and which we call mesoscopic groups. I
 n this\ntalk I will introduce these ideas\, the role they play in functori
 ality\, and\nopen problems that arise in their study. Time permitting\, I 
 will explain\nthe role they play in refining the stable trace formula.\n
