In this talk I will focus on BPS states in supersymmetric field theories with N=2. In this theories one can consider a certain class of supersymmetric line operators. Such operators support a new class of BPS states, called framed BPS states. I will discuss a formalism based on quivers to understand these objects and their properties. Time permitting I will discuss a relation with the theory of cluster algebras.
