摘要: Abstract In this paper we study the category C m ( P ) of -cyclic complexes over , where is projective modules a finite dimensional hereditary algebra A and describe almost split sequences in . This applied to prove existence Hall polynomials when representation ≠ 1 We further introduce its localization sense Bridgeland. case finite, use define generic Bridgeland–Hall show that it contains subalgebra isomorphic integral form corresponding quantum enveloping algebra. provides construction simple Lie associated with
