BPS spectra and BPS quivers
In this talk I will briefly present the relation between the spectrum of BPS states in 4D N=2 quantum field theories and a notion of BPS quiver. I will present how to construct such an object knowing all BPS states and (what is more interesting) how to obtain BPS spectrum from BPS quiver. My talk will be based on the paper "N=2 QFT and Their BPS Quivers" [1112.3984].
