Isoperimetric inequalities on slabs with applications to cubes and Gaussian slabs

Communications on Pure and Applied Mathematics, Volume 79, Issue 4, Page 1012-1072, April 2026.
Abstract We study isoperimetric inequalities on “slabs”, namely weighted Riemannian manifolds obtained as the product of the uniform measure on a finite length interval with a codimension‐one base. As our two main applications, we consider the case when the base is the flat torus R2/2Z2$\mathbb {R}^2 / 2 \mathbb {Z}^2$ and the standard Gaussian measure

Time as a geometric property of space

Frontiers in Physics, 2016
The proper description of time remains a key unsolved problem in science. Newton conceived of time as absolute and universal which it `flows equably without relation to anything external'}.

Conformal invariants of Minkowski space [PDF]

Proceedings of the American Mathematical Society, 1985
The conformal invariant defined for compact Riemannian manifolds by Yamabe is generalized to pseudo-Riemannian manifolds and is shown to be nontrivial for Minkowski space. We also make some elementary remarks about generalizations of Yamabe’s equation to sections of vector bundles, as have been studied by physicists concerned with Goldstone bosons and ...

Langevin simulation in Minkowski space?

Physics Letters B, 1985
Abstract We present in this paper a “tentative”, “formal” proof that the Langevin simulation for relativistic systems can be performed directly in Minkowski space without rotating to euclidean time. The proof bypasses the difficult task of studying the spectrum of the non-self-adjoint Fokker-Planck hamiltonian and it is based on a dimensional ...

Elastic Sturmian spirals in the Lorentz-Minkowski plane

Open Mathematics, 2016
In this paper we consider some elastic spacelike and timelike curves in the Lorentz-Minkowski plane and obtain the respective vectorial equations of their position vectors in explicit analytical form.

Gauge theory on ρ-Minkowski space-time

Journal of High Energy Physics
We construct a gauge theory model on the 4-dimensional ρ-Minkowski space-time, a particular deformation of the Minkowski space-time recently considered. The corresponding star product results from a combination of Weyl quantization map and properties of ...
