Identities for Schur-type determinants and pfaffians
David Anderson, William Fulton
We give a simple formula for some determinants, and an analogous formula for pfaffians, both of which are polynomial identities. The second involve some expressions that interpolat…
Schubert Polynomials in Types A and C
David Anderson, William Fulton
Enriched versions of type A Schubert polynomials are constructed with coefficients in a polynomial ring in variables . Specializing these variables to recover…
Vexillary signed permutations revisited
David Anderson, William Fulton
We study the combinatorial properties of vexillary signed permutations, which are signed analogues of the vexillary permutations first considered by Lascoux and Schützenberger. We…
Pattern Avoiding Linear Extensions of Rectangular Posets
David Anderson, Eric S. Egge, Manda Riehl +3
Inspired by Yakoubov's 2015 investigation of pattern avoiding linear extensions of the posets called combs, we study pattern avoiding linear extensions of rectangular posets. These…
A note on quantum products of Schubert classes in a Grassmannian
Dave Anderson
Given two Schubert classes and in the quantum cohomology of a Grassmannian, we construct a partition , depending on and , such that appears with coeffic…
