摘要
Suppose mu is a partition of n and lambda a composition of n, and let S-mu, M-lambda denote the Specht module and permutation module defined by Dipper and James for the Iwahori-Hecke algebra H-n of the symmetric group W-n. We give an explicit fast algorithm for expressing a tableau homomorphism (phi) over cap (A) : S-mu -%26gt; M-lambda a linear combination of semistandard homomorphisms. Along the way we provide a utility result related to removing rows from tableaux.
