Tropicalization, symmetric polynomials, and complexity

Alexander Woo, Alexander Yong

D. Grigoriev-G. Koshevoy recently proved that tropical Schur polynomials have (at worst) polynomial tropical semiring complexity. They also conjectured tropical skew Schur polynomi…

Vanishing of Littlewood-Richardson polynomials is in P

Anshul Adve, Colleen Robichaux, Alexander Yong

J. DeLoera-T. McAllister and K. D. Mulmuley-H. Narayanan-M. Sohoni independently proved that determining the vanishing of Littlewood-Richardson coefficients has strongly polynomial…

K-orbit closures and Barbasch-Evens-Magyar varieties

Laura Escobar, Benjamin J. Wyser, Alexander Yong

We define the Barbasch-Evens-Magyar varieties. We show they are isomorphic to the smooth varieties defined in [D.~Barbasch-S.~Evens '94] that map generically finitely to symmetric…

Symmetric group representations and Z

Anshul Adve, Alexander Yong

We discuss implications of the following statement about the representation theory of symmetric groups: every integer appears infinitely often as an irreducible character evaluatio…

Newton polytopes and symmetric Grothendieck polynomials

Laura Escobar, Alexander Yong

Symmetric Grothendieck polynomials are inhomogeneous versions of Schur polynomials that arise in combinatorial -theory. A polynomial has saturated Newton polytope (SNP) if every…

Newton Polytopes in Algebraic Combinatorics

Cara Monical, Neriman Tokcan, Alexander Yong

A polynomial has saturated Newton polytope (SNP) if every lattice point of the convex hull of its exponent vectors corresponds to a monomial. We compile instances of SNP in algebra…
