On the relation between pseudocharacters and Chenevier's determinants
Bulletin of the London Mathematical Society, Volume 56, Issue 12, Page 3721-3730, December 2024.Abstract Consider a commutative unital ring A$A$ and a unital A$A$‐algebra R$R$. Let d$d$ be a positive integer. Chenevier proved that when (2d)!$(2d)!$ is invertible in A$A$, the map associating to a determinant its trace is a bijection between A$A$‐valued d$d$‐dimensional determinants of R$R$ and A$A$‐valued d$d$‐dimensional pseudocharacters of R$R$.

Journal of the London Mathematical Society, Volume 110, Issue 5, November 2024.Abstract For a log Calabi Yau pair (X,D$X,D$) with X∖D$X\setminus D$ smooth affine, satisfying either a maximal degeneracy assumption or contains a Zariski dense torus, we prove under the condition that D is the support of a nef divisor that the structure constants defining a trace form on the mirror algebra constructed by Gross–Siebert are given by ...

The anisotropic Calderón problem at large fixed frequency on manifolds with invertible ray transform
Journal of the London Mathematical Society, Volume 110, Issue 4, October 2024.Abstract We consider the inverse problem of recovering a potential from the Dirichlet to Neumann map at a large fixed frequency on certain Riemannian manifolds. We extend the earlier result of Uhlmann and Wang [arXiv:2104.03477] to the case of simple manifolds, and more generally to manifolds where the geodesic ray transform is stably invertible.

Open MathematicsThis article aims to delve deeper into the weighted grand variable Herz-Morrey spaces, and try to establish the boundedness of fractional sublinear operators and their multilinear commutators within this framework.

Fortschritte der Physik, Volume 72, Issue 5, May 2024.Abstract The diffeomorphism class of simply connected smooth Calabi‐Yau threefolds with torsion‐free cohomology is determined via certain basic topological invariants: the Hodge numbers, the triple intersection form, and the second Chern class.

A brief survey of Nigel Kalton's work on interpolation and related topics [PDF]
, 2014 This is the third of a series of papers surveying some small part of the remarkable work of our friend and colleague Nigel Kalton. We have written it as part of a tribute to his memory. It does not contain new results.

Mixed weak‐type inequalities in Euclidean spaces and in spaces of the homogeneous type
Mathematische Nachrichten, Volume 297, Issue 4, Page 1370-1406, April 2024.Abstract In this paper, we provide mixed weak‐type inequalities generalizing previous results in an earlier work by Caldarelli and the second author and also in the spirit of earlier results by Lorente et al. One of the main novelties is that, besides obtaining estimates in the Euclidean setting, results are provided as well in spaces of the ...

Airy structures and deformations of curves in surfaces
Journal of the London Mathematical Society, Volume 109, Issue 1, January 2024.Abstract An embedded curve in a symplectic surface Σ⊂X$\Sigma \subset X$ defines a smooth deformation space B$\mathcal {B}$ of nearby embedded curves. A key idea of Kontsevich and Soibelman is to equip the symplectic surface X$X$ with a foliation in order to study the deformation space B$\mathcal {B}$.

Equivariant resolutions over Veronese rings
Journal of the London Mathematical Society, Volume 109, Issue 1, January 2024.Abstract Working in a polynomial ring S=k[x1,…,xn]$S={\mathbf {k}}[x_1,\ldots ,x_n]$, where k${\mathbf {k}}$ is an arbitrary commutative ring with 1, we consider the d$d$th Veronese subalgebras R=S(d)$R={S^{(d)}}$, as well as natural R$R$‐submodules M=S(⩾r,d)$M={S^{({\geqslant r},{d})}}$ inside S$S$.

Buildings, valuated matroids, and tropical linear spaces
Journal of the London Mathematical Society, Volume 109, Issue 1, January 2024.Abstract Affine Bruhat–Tits buildings are geometric spaces extracting the combinatorics of algebraic groups. The building of PGL$\mathrm{PGL}$ parameterizes flags of subspaces/lattices in or, equivalently, norms on a fixed finite‐dimensional vector space, up to homothety.
