DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/2/">Do
 main Wall Junctions and Categorical Wall-Crossing</a>\nby Ahsan Khan (Rutg
 ers University) as part of NHETC Seminar\n\n\nAbstract\nThe wall-crossing 
 property of BPS states is an important feature common to centrally extende
 d supersymmetric field theories. In this talk I will describe how the phys
 ics of domain wall junctions combined with elementary ideas in homological
  algebra leads to a categorical wall-crossing formula\; a universal descri
 ption of how BPS Hilbert spaces jump across a wall of marginal stability. 
 \n\nBased on an upcoming paper with Greg Moore.\n
