Quiver varieties and quantum affine algebras. (English. Japanese original) Zbl 1246.17021
Sugaku Expo. 19, No. 1, 53-78 (2006); translation from Sūgaku 52, No. 4, 337-359 (2000).
This is mainly an introduction of expository nature to quiver varieties and their applications, however also new results relating quiver varieties to quantum enveloping algebras of affine Lie algebras and their finite-dimensional representations are presented. First the author explains the construction of algebras via convolution products and geometric constructions of quantized enveloping algebras due to Ringel and Lusztig. Then the definition of quiver varieties is given and their relations to (non-affine) quantum enveloping algebras is explained.
