Degenerations in tropical compactifications and tropical intersection theory of
Sean T. Griffin, Jake Levinson, Rohini Ramadas +1
The main result of this paper is a formula for the limit cycle of a 1-parameter family of subvarieties of a tropical compactification, expressed in terms of tropical intersections.…
Fundamental groups of moduli spaces of real weighted stable curves
Jake Levinson, Haggai Liu
The ordinary and -equivariant fundamental groups of the moduli space of real -marked stable curves of genus are known as \emph{ca…
A proof of a conjecture by Monin and Rana on equations defining
Maria Gillespie, Sean T. Griffin, Jake Levinson
Monin and Rana conjectured a set of equations defining the image of the moduli space under an embedding into due…
Degenerations and multiplicity-free formulas for products of and classes on
Maria Gillespie, Sean T. Griffin, Jake Levinson
We consider products of classes and products of classes on . For each product, we construct a flat family of subschemes of whos…
Class groups of open Richardson varieties in the Grassmannian are trivial
Jake Levinson, Kevin Purbhoo
We prove that the divisor class group of any open Richardson variety in the Grassmannian is trivial. Our proof uses Nagata's criterion, localizing the coordinate ring at a suitable…
