A polynomial generalization of the power-compositions determinant

Josep M. Brunat, Antonio Montes

Let $C (n, p)$ be the set of $p$ -compositions of an integer $n$ , i.e., the set of $p$ -tuples $α = (α_{1}, ..., α_{p})$ of nonnegative integers such that $α_{1} + ... + α_{p} = n$ , and $\mathbf{x}=(…

Some composition determinants

J. M. Brunat, C. Krattenthaler, A. Lascoux +1

We compute two parametric determinants in which rows and columns are indexed by compositions, where in one determinant the entries are products of binomial coefficients, while in t…
