On the apparent failure of the topological theory of phase transitions
, 2015 The topological theory of phase transitions has its strong point in two theorems proving that, for a wide class of physical systems, phase transitions necessarily stem from topological changes of some submanifolds of configuration space.

Methods in Ecology and Evolution, Volume 17, Issue 3, Page 963-978, March 2026.Abstract In group‐living animals, relationships between group members are often highly differentiated. Some dyads can maintain strong and long‐lasting relationships, while others are only connected by weak or fleeting ties. More and more studies show that aspects of social relationships are related to reproductive success and survival.

Developmental Science, Volume 29, Issue 2, March 2026.ABSTRACT Languages differ in how words carve up the world into categories, and these differences in lexical categories often influence how speakers interpret perceived events. Past research has shown that languages with a single and general word for one domain tend to cue attention more broadly than languages with multiple, more specific verbs.

New Phytologist, Volume 249, Issue 6, Page 2986-3002, March 2026.Summary The vesicle trafficking system enables multidirectional cargo fluxes between endomembrane compartments. However, vesicle trafficking plays dual roles during pathogen infections. In plants, it mediates autophagic immune responses but can also be hijacked by pathogens to facilitate successful infections.

The saturation number for the diamond is linear
Bulletin of the London Mathematical Society, Volume 58, Issue 3, March 2026.Abstract For a fixed poset P$\mathcal {P}$ we say that a family F⊆P([n])$\mathcal {F}\subseteq \mathcal {P}([n])$ is P$\mathcal {P}$‐saturated if it does not contain an induced copy of P$\mathcal {P}$, but whenever we add a new set to F$\mathcal {F}$, we form an induced copy of P$\mathcal {P}$.

On universal‐homogeneous hyperbolic graphs and spaces and their isometry groups
Bulletin of the London Mathematical Society, Volume 58, Issue 3, March 2026.Abstract The Urysohn space is the unique separable metric space that is universal and homogeneous for finite metric spaces, that is, it embeds any finite metric space any isometry between finite subspaces extends to an isometry of the whole space. We here consider the existence of a universal‐homogeneous hyperbolic space. We show that for δ>0$\delta >0$

Fixed‐point posets of groups and Euler characteristics
Bulletin of the London Mathematical Society, Volume 58, Issue 3, March 2026.Abstract Suppose that G$G$ is a group and Ω$\Omega$ is a G$G$‐set. For X$\mathcal {X}$ a set of subgroups of G$G$, we introduce the fixed‐point poset XΩ$\mathcal {X}_{\Omega }$. A variety of results concerning XΩ$\mathcal {X}_{\Omega }$ are proved as, for example, in the case when p$p$ is a prime and X$\mathcal {X}$ is a non‐empty set of finite non ...

Markov Chains with Stochastically Stationary Transition Probabilities
The Annals of Probability, 1991 In this special invited paper, the author combines a partial summary of results of Nawrotzki and Cogburn on Markov chains whose transition probabilities form a stationary process with new contributions. Section 1 serves to introduce the model: \((\Theta,{\mathcal B}_ 0)\) is a measurable space, \(\Omega=\Theta^{\mathbb{Z}}\), \(\Theta_ n\) the \(n\)-th

Determinacy on the edge of second‐order arithmetic, I
Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.Abstract This is the first of two articles on the strength of m$m{}$‐Σ30$\bm{\Sigma }^0_3{}$‐determinacy for m∈N$m\in \mathbb {N}$, the strongest theories of determinacy contained in Hilbert's second‐order arithmetic (Z2)$(Z_2)$. In this article, we refute two natural conjectures on the strength of these principles in terms of inductive definability ...

Fusion systems related to polynomial representations of SL2(q)$\operatorname{SL}_2(q)$
Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.Abstract Let q$q$ be a power of a fixed prime p$p$. We classify up to isomorphism all simple saturated fusion systems on a certain class of p$p$‐groups constructed from the polynomial representations of SL2(q)$\operatorname{SL}_2(q)$, which includes the Sylow p$p$‐subgroups of GL3(q)$\mathrm{GL}_3(q)$ and Sp4(q)$\mathrm{Sp}_4(q)$ as special cases.
