On the monotonicity of affine quermassintegrals

Shibing Chen, Yuanyuan Li, Xianduo Wang ยท 2026

Lutwak's affine quermassintegral theory is a foundational component of modern affine Brunn--Minkowski theory. Developed in the 1980s, it provides affine analogues of the classical quermassintegrals anโ€ฆ

Faces of invariant convex sets in representations of nontrivial copolarity

Yi Shi ยท 2026

Let $(V, G)$ be an orthogonal representation of a compact Lie group $G$ with nontrivial copolarity, and $\Sigma$ a fat section of $(V, G)$. If $E$ is a $G$-invariant compact convex set in $V$, then $Pโ€ฆ

Self perimeter of convex sets

Gershon Wolansky ยท 2026

This paper introduces a natural definition for the volume of the unit ball in $n$-dimensional normed spaces $\mathbb{R}^n$. This definition preserves the Euclidean relation $P(B)/V(B)=n$ between the pโ€ฆ

Uniform estimates and Brezis-Merle type inequalities for the $k$-Hessian equation

Jie Deng, Haibin Wang, Bin Zhou ยท 2026

In this paper, we prove a Brezis-Merle type inequality for $k$-convex functions vanishing on the boundary. As an application, we establish an Alexandrov-Bakelman-Pucci type estimate for the intermediaโ€ฆ

Measure preserving maps with bounded total variation

Stefano Bianchini, Luca Talamini ยท 2026

Consider a piecewise affine Lipschitz map $\phi : \Omega \to \mathbb R$, where $\Omega \subset \mathbb R^d$ is an open set, and assume that $x \mapsto x + t \nabla \phi(x)$ is injective for almost eveโ€ฆ

Geometric inequalities and the Alexandrov-Bakelman-Pucci technique

S. Brendle ยท 2026

In this expository paper, we discuss a unified framework for proving various geometric inequalities, based on the so-called Alexandrov-Bakelman-Pucci technique. Examples include Cabr\'e's proof of theโ€ฆ

Failing to keep the balance: explicit formulae and topological recursion for leaky Hurwitz numbers

Marvin Anas Hahn, Reinier Kramer ยท 2026

Recently a new family of enumerative invariants called leaky Hurwitz numbers was introduced by Cavalieri-Markwig-Ranganathan in the context of logarithmic intersection theory. They admit an interpretaโ€ฆ

Metric embeddings of cubes into dense subsets of cubes

Miltiadis Karamanlis, Cosmas Kravaris ยท 2026

Fix $k \in \mathbb{N}$ and $0 < \delta < 1$. We study how large $N$ must be so that every $\delta$-dense subset $\mathcal{D} \subset \{0,1\}^N$ (meaning $|\mathcal{D}| \geq \delta 2^N$) contains the iโ€ฆ

Stability of optimal transport on metric measure spaces

Bang-Xian Han, Zhuo-Nan Zhu ยท 2026

We prove a quantitative stability of Kantorovich potentials on metric measure spaces with lower Ricci curvature bound, thereby confirming a recent conjecture of Kitagawa, Letrouit and M\'erigot. Our pโ€ฆ

Sharp global Alexandrov estimates and entire solutions of Monge-Amp\`ere equations

Tianling Jin, Xushan Tu, Jingang Xiong ยท 2026

This paper continues our work [19] on sharp Alexandrov estimates. We obtain a sharp global uniform distance estimate from a convex function to the class of unimodular convex quadratic polynomials in tโ€ฆ

Extremal Alexandrov estimates: singularities, obstacles, and stability

Tianling Jin, Xushan Tu, Jingang Xiong ยท 2026

The classical Alexandrov estimate controls the oscillation of a convex function by the mass of its associated Monge-Amp\`ere measure and yields, for two convex functions of $n$ variables with the sameโ€ฆ

Shallow $T_{bc}$ states from an EFT analysis of $B^{(*)} \bar D^{(*)}$ scattering on the lattice

Michael Abolnikov, Lu Meng, Vadim Baru, Evgeny Epelbaum, Arseniy A. Filin, Ashot M. Gasparyan ยท 2026

We present an effective field theory (EFT) framework for coupled-channel $B^{(*)}\bar D^{(*)}$ scattering, applying it to recent lattice QCD results by Alexandrou et al. [Phys. Rev. Lett. 132, 151902 โ€ฆ
