Abstract: N=2 gauge theories are considered from the point of view of the representation theory of their (equivalence class) of quivers, or equivalently of basic (associative) algebra. The key observation is the strict relation between the Ringel theory of tame associative algebras and the N=2 SU(2) gauge theories. This can be generalized to an arbitrary gauge group, leading to a satisfactory algebraic theory of N=2 gauge models.
