A proof of a conjecture by Monin and Rana on equations defining $M ˉ_{0, n}$

Maria Gillespie, Sean T. Griffin, Jake Levinson

Monin and Rana conjectured a set of equations defining the image of the moduli space $M ˉ_{0, n}$ under an embedding into $P^{1} \times \dots \times P^{n - 3}$ due…

$Δ$ -Springer varieties and Hall-Littlewood polynomials

Sean T. Griffin

The $Δ$ -Springer varieties are a generalization of Springer fibers introduced by Levinson, Woo, and the author that have connections to the Delta Conjecture from algebraic combinat…

Orbit harmonics for the union of two orbits

Sean T. Griffin

Garsia and Procesi, in their study of Springer's representation, proved that the cohomology ring of a Springer fiber is isomorphic to the associated graded ring of the coordinate r…

Degenerations and multiplicity-free formulas for products of $ψ$ and $ω$ classes on $M_{0, n}$

Maria Gillespie, Sean T. Griffin, Jake Levinson

We consider products of $ψ$ classes and products of $ω$ classes on $M_{0, n + 3}$ . For each product, we construct a flat family of subschemes of $M_{0, n + 3}$ whos…

Lazy tournaments and multidegrees of a projective embedding of $M_{0, n}$

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…

Existence and hardness of conveyor belts

Molly Baird, Sara C. Billey, Erik D. Demaine +7

An open problem of Manuel Abellanas asks whether every set of disjoint closed unit disks in the plane can be connected by a conveyor belt, which means a tight simple closed curve t…
