Nakajima varieties are very remarkable algebraic symplectic varieties that can be associated to an arbitrary multigraph (which later in the theory plays the role of the Dynkin diagram of a certain Lie algebra). They include, for example, cotangent bundles of partial flag varieties, as well as Hilbert schemes of points and more general moduli spaces of sheaves on ADE surfaces. This talk will be an introduction to the subject.
