Asymptotics of multinomial sums and identities between multi-integrals



We calculate the asymptotics of combinatorial sums ∑αf(α)(αn)β, whereα = (α1, …,αh) withαi =αj for certaini, j. Hereh is fixed and theαi’s are natural numbers. This implies the asymptotics of the correspondingSn-character degrees ∑λf(λ)dλβ. For certain sequences ofSn characters which involve Young’s rule, the latter asymptotics were obtained earlier [1] by a different method. Equating the two asymptotics, we obtain equations between multi-integrals which involve Gaussian measures. Special cases here give certain extensions of the Mehta integral [5], [6].
