Dominant permutations, positive mixed-variable formulas, and product-splitting equivalence for (double) Schubert polynomials

Matthew J. Samuel

We present new positive combinatorial formulas for triple Schubert coefficients in mixed-variable products of double Schubert polynomials, $S_{u} (x; y) S_{v} (x; z)$ ,…

Triple Quantum Schubert Calculus

Matthew J. Samuel

We prove a triple quantum Pieri formula: the product of a quantum double Schubert polynomial $S_{u} (x; y)$ by a quantum factorial elementary polynomial $\wideti…

The Schubert bialgebra

Matthew J. Samuel

We introduce a Schubert bialgebra $A = ⨁_{n \geq 0} Z [x_{1}, \dots, x_{n}]$ , in which polynomials in different numbers of variables multiply to zero and the copro…

A Littlewood-Richardson Rule for Forest Polynomials

Matthew J. Samuel

The forest polynomials $P_{a}$ of Nadeau-Tewari form a $Z$ -basis of $Z [x_{1}, x_{2}, \dots]$ whose role for the cohomology of the quasisymmetric flag variety…
