AR-quiver approach to affine canonical basis elements

[摘要] This is the continuation of [Y. Li, Affine quivers of type (A) over tilde (n) and canonical bases, math.QA/0501175]. We describe the affine canonical basis elements in the case when the affine quiver has arbitrary orientation. This generalizes the description in [G. Lusztig, Affine quivers and canonical bases, Publ. Math. Inst. Hautes Etudes Sci. 76 (1992) 111-163]. (c) 2007 Elsevier Inc. All rights reserved.
