On the positivity and integrality of coefficients of mirror maps

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 8, August 2026.
Abstract We present natural conjectural generalisations of the ‘positivity and integrality of mirror maps’ phenomenon, encompassing the mirror maps appearing in the Batyrev–Borisov construction of mirror Calabi–Yau complete intersections in Fano toric varieties as a special case.

Star-products for Lie-algebraic noncommutative Minkowski space-times

open access: yesJournal of High Energy Physics
Poisson structures of the Poincaré group can be linked to deformations of the Minkowski space-time, classified some time ago by Zakrewski. Based on this classification, various quantum Minkowski space-times with coordinates Lie algebras and specific ...

A short proof of a central limit theorem for the order of the giant component and k$k$‐core

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 8, August 2026.
Abstract In this note we outline a new and simple approach to proving central limit theorems for various ‘global’ graph parameters that have robust ‘local’ approximations, using the Efron–Stein inequality, which relies on a combinatorial analysis of the stability of these approximations under resampling an edge.

Christoffel and Minkowski problems in Minkowski space

open access: yesSéminaire de théorie spectrale et géométrie, 2015
For convex sets in the Lorentzian Minkowski space bounded by space-like hyperplanes, it is possible to define area measures, similarly to the classical definition for convex bodies in the Euclidean space. Here the measures are defined on the hyperbolic space rather than on the round sphere.

Minkowski box from Yangian bootstrap

open access: yesJournal of High Energy Physics, 2021
We extend the recently developed Yangian bootstrap for Feynman integrals to Minkowski space, focusing on the case of the one-loop box integral. The space of Yangian invariants is spanned by the Bloch-Wigner function and its discontinuities.

On the deterministic interior body of random polytopes

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract Let {Xi}i=1∞$\lbrace X_i\rbrace _{i=1}^{\infty }$ be a sequence of independent copies of a random vector X$X$ in Rn$\mathbb {R}^n$. We revisit the question to determine the asymptotic shape of the random polytope KN=conv{X1,…,XN}$K_N={\rm conv}\lbrace X_1,\ldots,X_N\rbrace$ where N>n$N>n$.

Quantum complex Minkowski space [PDF]

open access: yesJournal of Geometry and Physics, 2006
The complex Minkowski phase space has the physical interpretation of the phase space of the scalar massive conformal particle. The aim of the paper is the construction and investigation of the quantum complex Minkowski space.

Risk‐aware safe reinforcement learning for control of stochastic linear systems

open access: yesAsian Journal of Control, Volume 28, Issue 4, Page 1649-1672, July 2026.
Abstract This paper presents a risk‐aware safe reinforcement learning (RL) control design for stochastic discrete‐time linear systems. Rather than using a safety certifier to myopically intervene with the RL controller, a risk‐informed safe controller is also learned besides the RL controller, and the RL and safe controllers are combined together ...

Isoparametric hypersurfaces in Minkowski spaces

open access: yesDifferential Geometry and its Applications, 2016
In this paper, we introduce isoparametric functions and isoparametric hypersurfaces in Finsler manifolds and give the necessary and sufficient conditions for a transnormal function to be isoparametric. We then prove that hyperplanes, Minkowski hyperspheres and $F^*$-Minkowski cylinders in a Minkowski space with $BH$-volume (resp.

Discover Class‐Based Feature Distribution by Encoding Discrete Data for Classification

open access: yesExpert Systems, Volume 43, Issue 7, July 2026.
ABSTRACT The self‐organisation map is an unsupervised learning technique that discovers patterns and relationships in data without requiring labelled training data. Inspired by the self‐organisation map, Self‐Organised Granular encoding has been shown to be effective for generating reliable discrete data clustering results as it is a data encoding ...
