BPS spectra of N=2 QFT in 4d

I will discuss how quivers can be used to describe BPS spectra of N=2 QFT in 4d. The quivers characterize a basis of BPS particles, the spectrum can be thought of as bound-states of the basis particles. The jumping of the spectrum between different members of the same deformation family of theories will be described as well as a method for the computation of BPS spectra for a large class of theories.
