摘要:
Let Gamma be a quiver containing finite cyclic blocks and Pi(lambda) (Gamma) be the deformed preprojective algebra of Gamma. It is proved that a suitable quotient u(q) of Pi(lambda) (Gamma) for an appropriate vector lambda is a finite-dimensional quantum group. Some properties of u(q) are also obtained. An isomorphism as Hopf algebras is given between u(q) and a restricted quantum group U-q (sl(2)). (C) 2004 Elsevier Inc. All rights reserved.
