Abstract

Language:

The combinatorial R matrices are obtained for a family {Bl} of crystals for U ′q(C(1)n) and U ′q(A(2)2n−1), where Bl is the crystal of the irreducible module corresponding to the one-row Young diagram of length l. The isomorphism Bl⊗Bk ≃ Bk⊗Bl and the energy function are described explicitly in terms of a Cn-analogue of the Robinson-Schensted-Knuth type insertion algorithm. As an application, a C(1)n-analogue of the Kostka polynomials is calculated for several cases.
