Uniform Poincaré-Sobolev and isoperimetric inequalities for classes of domains

open access: yes, 2015
The aim of this paper is to prove an isoperimetric inequality relative to a convex domain in R^d intersected with balls with a uniform relative isoperimetric constant, independent of the size of the radius r>0 and the position of the center of the ball ...

Quantitative isoperimetric inequalities in H^n [PDF]

open access: yes, 2015
In the Heisenberg group H^n we prove quantitative isoperimetric inequalities for Pansu's spheres, that are known to be isoperimetric under various assumptions.

An Expository Lecture of María Jesús Chasco on Some Applications of Fubini’s Theorem

open access: yesAxioms, 2021
The usefulness of Fubini’s theorem as a measurement instrument is clearly understood from its multiple applications in Analysis, Convex Geometry, Statistics or Number Theory. This article is an expository paper based on a master class given by the second

Isoperimetric inequalities in nonlocal diffusion problems with integrable kernel [PDF]

open access: yesOpuscula Mathematica
We deduce isoperimetric estimates for solutions of linear stationary and evolution problems. Our main result establishes the comparison in norm between the solution of a problem and its symmetric version when nonlocal diffusion defined through integrable

On Non Local p-Laplacian with Right Hand Side Radon Measure

open access: yesFractal and Fractional, 2022
The aim of this paper is to investigate the following non local p-Laplacian problem with data a bounded Radon measure ϑ∈Mb(Ω): (−Δ)psu=ϑinΩ, with vanishing conditions outside Ω, and where s∈(0,1),2 ...

Exponential convergence for ultrafast diffusion equations with log‐concave weights

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.
Abstract We study the asymptotic behavior of a weighted ultrafast diffusion PDE on the real line, with a log‐concave and log‐lipschitz weight, and prove exponential convergence to equilibrium. This result goes beyond the compact setting studied in Iacobelli [Discrete Contin. Dyn. Syst. 39 (2019), 4929–4943].

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$N>n$.

Reifenberg’s isoperimetric inequality revisited [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2019
We prove a generalization of Reifenberg's isoperimetric inequality. The main result of this paper is used to establish existence of a minimizer for an anisotropically-weighted area functional among a collection of surfaces which satisfies a set of axioms, namely being closed under certain deformations and Hausdorff limits.
