A priori estimates and large population limits for some nonsymmetric Nash systems with semimonotonicity

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 1, Page 3-88, January 2026.
Abstract We address the problem of regularity of solutions ui(t,x1,…,xN)$u^i(t, x^1, \ldots, x^N)$ to a family of semilinear parabolic systems of N$N$ equations, which describe closed‐loop equilibria of some N$N$‐player differential games with Lagrangian having quadratic behaviour in the velocity variable, running costs fi(x)$f^i(x)$ and final costs gi(

Integrating Aegean Last Interglacial faunas into the Mediterranean palaeobiogeographic framework: New evidence from Karpathos (Greece)

open access: yesJournal of Quaternary Science, Volume 41, Issue 1, Page 80-98, January 2026.
ABSTRACT The Last Interglacial (LIG) or Marine Isotope Stage (MIS) 5e, spanning 129 to 116 kyrs ago, is recognised as one of the warmest periods in the Quaternary, with global sea surface temperatures (SSTs) 1°C–2°C higher than today, sea levels 5–10 m above the current level and biogeographical range expansion of specific tropical species into the ...

Plank theorems and their applications: A survey

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract Plank problems concern the covering of convex bodies by planks in Euclidean space and are related to famous open problems in convex geometry. In this survey, we introduce plank problems and present surprising applications of plank theorems in various areas of mathematics.

Constructive Matrix Theory for Higher Order Interaction

open access: yes, 2019
This paper provides an extension of the constructive loop vertex expansion to stable matrix models with interactions of arbitrarily high order. We introduce a new representation for such models, then perform a forest expansion on this representation.

The relative variational principle by Ledrappier and Walters: A survey

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract Ledrappier and Walters's article “A Relativised Variational Principle for Continuous Transformations”, J. Lond. Math. Soc. (2) 16 (1977), no. 3, 568–576) is a landmark in the development of thermodynamic formalism. This survey, aimed at newcomers to the field and experts in adjacent fields discusses the background, the Ledrappier–Walters ...

The Theta Term in QCD Sum Rules and the Electric Dipole Moment of the Vector Meson

open access: yes, 1999
We demonstrate that the QCD sum rule method can be successfully applied to the calculation of CP-odd electromagnetic observables induced by a vacuum theta--angle. We implement the approach in calculating the electric dipole moment of the rho meson to ~30%

Combinatorics on number walls and the P(t)$P(t)$‐adic Littlewood conjecture

open access: yesMathematika, Volume 72, Issue 1, January 2026.
Abstract In 2004, de Mathan and Teulié stated the p$p$‐adic Littlewood conjecture (p$p$‐LC) in analogy with the classical Littlewood conjecture. Let Fq$\mathbb {F}_q$ be a finite field P(t)$P(t)$ be an irreducible polynomial with coefficients in Fq$\mathbb {F}_q$. This paper deals with the analogue of p$p$‐LC over the ring of formal Laurent series over

Quasi‐invariance of Gaussian measures for the 3d$3d$ energy critical nonlinear Schrödinger equation

open access: yesCommunications on Pure and Applied Mathematics, Volume 78, Issue 12, Page 2305-2353, December 2025.
Abstract We consider the 3d$3d$ energy critical nonlinear Schrödinger equation with data distributed according to the Gaussian measure with covariance operator (1−Δ)−s$(1-\Delta)^{-s}$, where Δ$\Delta$ is the Laplace operator and s$s$ is sufficiently large. We prove that the flow sends full measure sets to full measure sets. We also discuss some simple

Campylobacter Species Isolated From Wild Birds in Switzerland and Comparison to Isolates From Food and Human Origin

open access: yesMicrobiologyOpen, Volume 14, Issue 6, December 2025.
Campylobacter strains (Blue) from wild birds cluster with strains from poultry and human (red), showing dissemination of strains from wild birds via food to human. ABSTRACT Campylobacter species, a major cause of gastroenteritis, have been frequently isolated from wild birds.

Isospectral measures [PDF]

open access: yes, 2011
In recent papers a number of authors have considered Borel probability measures $\mu$ in $\br^d$ such that the Hilbert space $L^2(\mu)$ has a Fourier basis (orthogonal) of complex exponentials.
