schurRank
schurRank -- computes the dimension of the irreducible GL(QQ^n) representation associated to a partition
Synopsis
Usage:
schurRank(n, mu)
Inputs:
n
,
an
integer
, the size of the matrix group GL(QQ^n)
mu
,
a
list
, a partition (mu_1, ..., m_r) where mu_i is the number of boxes in the ith row
Outputs:
an
integer
, The dimension of the irreducible GL(QQ^n) representation associated to mu
Description
The dimension is computed using the determinantal formula given by the Weyl character formula.
i1 : schurRank(5, {4,3}) -- should be 560 o1 = 560
