【 摘 要 】

We find presentations for a family of semigroup algebras related to the problem of decomposing sl(3) (C) tensor products. Along the way we find new toric degenerations of the Grassmannian variety Gr(3)(C-n) which are T-invariant for T subset of GL(n)(C) the diagonal torus. (C) 2013 Elsevier Inc. All rights reserved.
