On the theories classified by an étendue

Bulletin of the London Mathematical Society, Volume 58, Issue 7, July 2026.
Abstract We give a model‐theoretic characterisation of the geometric theories classified by étendues—the ‘locally localic’ topoi. They are the theories where each model is determined, syntactically and semantically, by any witness of a fixed collection of formulae.

Affine hypersurfaces and superintegrable systems

Journal of the London Mathematical Society, Volume 114, Issue 1, July 2026.
Abstract It was recently shown that under mild assumptions, second‐order conformally superintegrable systems can be encoded in a (0,3)‐tensor, called structure tensor. For abundant systems, this approach led to algebraic integrability conditions that essentially allow one to restore a system from the knowledge of its structure tensor in a point on the ...

On exotic matrix exponential sums and Bessel–Speh functions

Journal of the London Mathematical Society, Volume 114, Issue 1, July 2026.
Abstract In a previous work with Carmon, we defined Bessel–Speh functions. These are matrix coefficients of irreducible Speh representations of GLkc(F)$\mathrm{GL}_{kc}(\mathbb {F})$, where F$\mathbb {F}$ is a finite field. They arise from (k,c)$(k,c)$ models, which are models that generalize the Whittaker model to Speh representations attached to ...

The Zarankiewicz problem on tripartite graphs

Journal of the London Mathematical Society, Volume 114, Issue 1, July 2026.
Abstract In 1975, Bollobás, Erdős, and Szemerédi asked for the smallest τ$\tau$ such that an n×n×n$n \times n \times n$ tripartite graph with minimum degree n+τ$n + \tau$ must contain Kt,t,t$K_{t, t, t}$, conjecturing that τ=O(n1/2)$\tau = \mathcal {O}(n^{1/2})$ for t=2$t = 2$.

On Dedekind's problem, a sparse version of Sperner's theorem, and antichains of a given size in the Boolean lattice

Journal of the London Mathematical Society, Volume 114, Issue 1, July 2026.
Abstract Dedekind's problem, dating back to 1897, asks for the total number ψ(n)$\psi (n)$ of antichains contained in the Boolean lattice Bn$B_n$ on n$n$ elements. We study Dedekind's problem using a recently developed method based on the cluster expansion from statistical physics, and as a result, obtain several new results on the number and typical ...
