... proved to be useful in the study of minimal components, in the dominance order of partitions, of Kr onecker products [14]. The number lr(λ, µ; π) can be described as an inner product of characters. ... Now, since ℓ(µ) = q, all entries of T i equal to q must be in row q of µ. Then µ q ≥ ρ(1) q + · · · + ρ(r) q ≥ rλ p . The claim follows. 4.4 Example. To illustrate th...
