Strict unimodality of q-binomial coefficients
Published 21 Jun 2013 in math.CO | (1306.5085v2)
Abstract: We prove strict unimodality of the q-binomial coefficients \binom{n}{k}_q as polynomials in q. The proof is based on the combinatorics of certain Young tableaux and the semigroup property of Kronecker coefficients of S_n representations.
