Large flats in large subgraphs of fine curve graphs

Ryan Dickmann, Roberta Shapiro · 2026

The fine curve graph of a surface is a graph whose vertices are essential simple closed curves and whose edges connect disjoint curves. Following a rich history of hyperbolicity of various graphs asso…

Birational boundedness of stable families

Paolo Cascini, Jihao Liu, Calum Spicer, Roberto Svaldi · 2026

We prove that normal projective stable families of maximal variation, of fixed dimension, and with bounded adjoint volume are birationally bounded. This is a consequence of a substantially stronger st…

Machine learning models for estimating counterfactuals in a single-arm inflammatory bowel disease study

Dan Liu, Fida K. Dankar, Jennifer C. deBruyn, Amanda Ricciuto, Anne M. Griffiths, Thomas D. Walters, Khaled EI Emam · 2026

Single-arm trials accelerate study timelines by reducing the number of patients that must be recruited for a concurrent control group. However, these designs require an alternative comparator to estim…

Liouville Type Results for Quasilinear Elliptic Inequalities Involving Gradient Terms on Weighted Graphs

Anh Tuan Duong, Yao Liu, Nguyen Cong Minh, Dao Trong Quyet, Yuhua Sun · 2026

In this paper, we study the following quasi-linear elliptic inequality $\Delta_m u +u^p |\nabla u|^q \leqslant 0$ on weighted graphs, where $(m,p,q)\in (1,\infty)\times\mathbb{R}\times\mathbb{R}$. Acc…

Melting temperature shifts from quantum fluctuations in generalized Wigner crystals

Aman Kumar, Sogoud Sherif, Veit Elser, Hitesh J. Changlani · 2026

It is generally believed that quantum fluctuations collaborate with thermal fluctuations, effectively reducing transition temperatures (e.g. for melting of charge order). We show that this is not alwa…
