Sign-reversing involutions in moduli spaces of curves
Vance Blankers, Maria Gillespie, Jake Levinson
We use sign-reversing involutions to solve two computational problems that arise naturally in the geometry of moduli spaces of curves. In particular, we give an explicit combinator…
Lazy tournaments and multidegrees of a projective embedding of
Maria Gillespie, Sean T. Griffin, Jake Levinson
We provide a new geometric interpretation of the multidegrees of the (iterated) Kapranov embedding $Φ_n:\overline{M}_{0,n+3}\hookrightarrow \mathbb{P}^1\times \mathbb{P}^2\times \c…
Schubert curves in the orthogonal Grassmannian
Maria Gillespie, Jake Levinson, Kevin Purbhoo
We develop a combinatorial rule to compute the real geometry of type B Schubert curves in the orthogonal Grassmannian , which are one-dimensional Schu…
Axioms for shifted tableau crystals
Maria Gillespie, Jake Levinson
We give local axioms that uniquely characterize the crystal-like structure on shifted tableaux developed in a previous paper by Gillespie, Levinson, and Purbhoo. These axioms close…
Shifted tableaux crystals
Maria Gillespie, Jake Levinson, Kevin Purbhoo
We introduce coplactic raising and lowering operators , , , and on shifted skew semistandard tableaux. We show that the primed operators and unprimed operato…
