Domain Wall Junctions and Categorical Wall-Crossing
Speaker: Ahsan Khan (Rutgers University)
The wall-crossing property of BPS states is an important feature common to centrally extended supersymmetric field theories. In this talk I will describe how the physics of domain wall junctions combined with elementary ideas in homological algebra leads to a categorical wall-crossing formula; a universal description of how BPS Hilbert spaces jump across a wall of marginal stability. Based on an upcoming paper with Greg Moore.
