CPT Student Seminar: BPS states, wall-crossing and quivers
In recent years it has become increasingly apparent that the study of BPS states is highly applicable not only to physics but several areas of mathematics as well. For example, BPS states are important objects in black hole physics, homological mirror symmetry and enumerative geometry. It is therefore important that we develop an efficient method of calculating the BPS states of a theory. This is made more complicated by the fact that the BPS spectrum discontinuously varies upon crossing certain surfaces in parameter space- giving rise to the so called 'wall-crossing phenomenon'. In this talk we develop the method of BPS quivers which gives us a way to understand all the BPS chambers of a theory in a purely combinatorial way.
