Idea

The term quiver variety refers to a number of algebraic varieties constructed as moduli spaces of quiver representations.

The most important are the Nakajima quiver varieties (Nakajima 98), which give the moduli of stable representations of preprojective algebras?. These are notable for allowing a geometrical construction of the universal enveloping algebra of Kac-Moody algebras acting on the cohomology of quiver varieties and related spaces.
