Abstract

It is shown that the gentle one-cycle algebra Λ(n1,1,1)\Lambda(n-1,1,1) has Hall polynomials. The Hall polynomials are explicitly given for all triples of indecomposable modules, and as a consequence, the Ringel--Hall Lie algebra of Λ(n1,1,1)\Lambda(n-1,1,1) is shown to be isomorphic to its Riedtmann Lie algebra.
