Every finite horizon Sinai billiard map has a unique measure of maximal entropy

Vaughn Climenhaga, Jason Day · 2026

Finite horizon Sinai billiard maps are examples of uniformly hyperbolic systems with singularities. These discontinuities make it more difficult to develop the classical theory of thermodynamic formal…

Hybrid Conjecture in a Mixed Shimura variety

Rodolphe Richard, Andrei Yafaev · 2026

The authors previously formulated the hybrid conjecture, unifying Andr\'e-Pink-Zannier and Andr\'e-Oort conjectures, and proved it in Shimura varieties of abelian type. We study its analogue for mixed…

UHECR doublets and their conditional association with nearby radio galaxies

Victor Barbosa Martins · 2026

The origin of ultra-high-energy cosmic rays (UHECRs) remains a fundamental question in astroparticle physics. While localized 3 $\sigma$ correlations with active galactic nuclei and starburst galaxies…

Spontaneous spherical symmetry breaking of black holes with resonant hair

Jose Ferreira, Carlos A. R. Herdeiro, Eugen Radu, Miguel Zilhao · 2026

Black holes with resonant hair are static, spherical, electrically charged solutions of the Einstein-Maxwell-(gauged-)scalar system. Scalar self-interactions are mandatory for their existence. Initial…

Piercing all maximum cliques in hypergraphs

Andreas Holmsen, Attila Jung, Balazs Keszegh, Daniel G. Simon, Gabor Tardos · 2026

Graphs whose maximum clique size exceeds half of the total number of vertices satisfy a classical property: the family of their maximum sized cliques can be pierced by a single vertex. This result dat…

Forecasting Ionospheric Irregularities on GNSS Lines of Sight Using Dynamic Graphs with Ephemeris Conditioning

Mert Can Turkmen, Eng Leong Tan, Yee Hui Lee · 2026

Most data-driven ionospheric forecasting models operate on gridded products, which do not preserve the time-varying sampling structure of satellite-based sensing. We instead model the ionosphere as a …

PAWN: Piece Value Analysis with Neural Networks

Ethan Tang, Hasan Davulcu, Jia Zou, Zhongju Zhang · 2026

Predicting the relative value of any given chess piece in a position remains an open challenge, as a piece's contribution depends on its spatial relationships with every other piece on the board. We d…

Combinatorial Contracts Through Demand Types

Elizabeth Baldwin, Paul Duetting, Michal Feldman, Maya Schlesinger · 2026

In the combinatorial action model of contract design, a principal delegates a complex project to an agent, incentivizing a subset of actions from a ground set of $n$ actions, via a linear contract. Co…

One-shot Compositional 3D Head Avatars with Deformable Hair

Yuan Sun, Xuan Wang, WeiLi Zhang, Wenxuan Zhang, Yu Guo, Fei Wang · 2026

We propose a compositional method for constructing a complete 3D head avatar from a single image. Prior one-shot holistic approaches frequently fail to produce realistic hair dynamics during animation…

On the $K$-extensions between Serre weights for unramified $\mathrm{GL}_3$

Yitong Wang · 2026

Let $p\geq5$ be a prime number. Let $L$ be a finite unramified extension of $\mathbb{Q}_p$ with ring of integers $\mathcal{O}_L$ and residue field $\mathbb{F}_q$. Given two Serre weights for $\mathrm{…

Liouville Theorems Above the Critical $9/2$ Threshold for Stationary Navier-Stokes Equations

Gaston Vergara-Hermosilla · 2026

We establish new Liouville-type theorems for the stationary Navier--Stokes equations in $\mathbb{R}^3$. A central open problem in this context is whether the classical $L^{9/2}(\mathbb{R}^3)$ conditio…

Between proper and square colorings of planar graphs with maximum degree at most four

Xujun Liu, Zihui Xu, Xin Zhang · 2026

An $i$-independent set is a vertex set whose pairwise distance is at least $i+1$. A proper (square) $k$-coloring of a graph $G$ is a partition of its vertex set into $k$ independent ($2$-independent) …

Implication semilattice of 990 quasigroup equational laws

Bruno Le Floch · 2026

In his quest to disprove a claim by Peirce that all lattices are distributive, Ernst Schr\"oder considered 135 years ago a list of 990 equational laws on quasigroups, analogous to associativity, such …
