Blown-up toric surfaces with non-polyhedral effective cone
We construct projective toric surfaces whose blow-up at a general point has a non-
polyhedral pseudo-effective cone. As a consequence, we prove that the pseudo-effective …

On an Equivalence of Divisors on from Gromov-Witten Theory and Conformal Blocks
L Chen, A Gibney, L Heller, E Kalashnikov… - Transformation …, 2024 - Springer
We consider a conjecture that identifies two types of base point free divisors on M¯ 0, n. The
first arises from Gromov-Witten theory of a Grassmannian. The second comes from first …

Symmetries and intrinsic vs. extrinsic properties of
S Park - arXiv preprint arXiv:2309.00758, 2023 - arxiv.org
We consider the following question: How much of the combinatorial structure determining
properties of $\overline {\mathcal {M} _ {0, n}} $ is``intrinsic''and how much new information …

Complete Subvarieties of and a Lifting Problem
D Choi - arXiv preprint arXiv:2304.08568, 2023 - arxiv.org
Finding the maximal dimension of complete subvarieties of the moduli space of smooth $ n $-
pointed curves of genus $ g $ is a long-standing open problem. Here we show that for $ g\ge …
