We prove the equivalence of several descriptions of generators of rings of semiinvariants of quivers, due to Domokos and Zubkov, Schofield and van den Bergh, and our earlier work. We also show that the dimensions of semi-invariants of weights nσ depend polynomially on n.
We give an involution type proof of the Littlewood-Richardson rule.
A graded poset structure is defined for sets of Littlewood-Richardson (LR) tableaux whose cardinalities are the multiplicities of irreducible gl(n)-modules in the tensor product of several irreducible gl(n)-modules indexed by rectangular partitions. This is a generalization of the cyclage poset on t
