Why Self-Supervised Encoders Want to Be Normal

Yuval Domb · 2026

We develop a geometric and information-theoretic framework for encoder-decoder learning built on the Information Bottleneck (IB) principle. Recasting IB as a rate-distortion problem with Kullback-Leib…

The quantum group structure of long-range integrable deformations

Koen Schouten, Marius de Leeuw · 2026

Quantum integrable spin chains are known to possess a large family of long-range deformations generated by the local, boost and bilocal operators. Although these deformations are well-understood on th…

Agnostically decoding gravitational wave model deficiencies in GWTC-3

Guillaume Dideron, Suvodip Mukherjee, Luis Lehner · 2026

Gravitational Wave (GW) data bring an exceptional avenue to test the underlying models of coalescing compact objects. In the regime of strong gravity and high curvature, they allow the exploration of …

Weakly, sufficiently or strongly localized operators on the Fock space in \mathh C^n

David Bekolle, Solange B. Difo, Hugues O. Defo, Edgar L. Tchoundja · 2026

We study properties of the following four classes of operators on the Fock space in $\mathbb C^n:$ 1) weakly localized operators; 2) sufficiently localized operators in the sense of Xia and Zheng; 3) …

Scalene Yang-Baxter maps and Lax triples

S. Konstantinou-Rizos, T. Kouloukas · 2026

We study a generalisation of the set-theoretic Yang-Baxter equation and investigate the connection between its solutions and matrix refactorisation problems. We refer to such solutions as scalene Yang…

On matrix Lax representations for (1+1)-dimensional evolutionary differential-difference equations

Sergei Igonin · 2026

Differential-difference matrix Lax representations (Lax pairs), gauge transformations, and discrete Miura-type transformations (MTs) belong to the main tools in the theory of (nonlinear) integrable di…

Nanohertz gravitational waves from the baryon-dark matter coincidence

Alessia Musumeci, Jacopo Nava, Silvia Pascoli, Filippo Sala · 2026

The nanohertz gravitational waves (GW) observed by pulsar timing arrays may originate from a cosmological first-order phase transition (PT) at $\sim$ 100 MeV. Taking this possibility seriously motivat…

The Nesting Bird Box Problem is ER-complete: Sharp Hardness Results for the Hidden Set Problem

Lucas Meijer, Till Miltzow, Johanna Ockenfels, Milos Stojakovic · 2026

In the (Nesting) Bird Box Problem we are given a polygonal domain P and a number k and we want to know if there is a set B of k points inside P such that no two points in B can see each other. The und…
