Super-entropic black holes in gravity’s rainbow and determining constraints on rainbow functions

European Physical Journal C: Particles and Fields
This paper is motivated by the application of the inverse isoperimetric inequality to establish constraints on the parameters of gravity’s rainbow. We investigate the thermodynamic (in)stability conditions for d-dimensional energy-dependent black holes ...

A full classification of the isometries of the class of ball‐bodies

Bulletin of the London Mathematical Society, Volume 57, Issue 12, Page 3691-3698, December 2025.
Abstract Complementing our previous results, we give a classification of all isometries (not necessarily surjective) of the metric space consisting of ball‐bodies, endowed with the Hausdorff metric. ‘Ball‐bodies’ are convex bodies which are intersections of translates of the Euclidean unit ball.

Fat equator effect and minimality in immersions and submersions of the sphere

Transactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.
Abstract Inspired by the equatorial concentration of measure phenomenon in the sphere, a result which is deduced from the general (and intrinsic), concentration of measure in Sn(1)$\mathbb {S}^n(1)$, we describe in this paper an equatorial concentration of measure satisfied by the closed (compact without boundary), isometric and minimal immersions x:Σm→

Horndeski gravity and the violation of reverse isoperimetric inequality

European Physical Journal C: Particles and Fields, 2017
We consider Einstein–Horndeski–Maxwell gravity, together with a cosmological constant and multiple Horndeski axions. We construct charged AdS planar black holes in general dimensions where the Horndeski axions span over the planar directions.

Curvature‐dimension condition of sub‐Riemannian α$\alpha$‐Grushin half‐spaces

Transactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.
Abstract We provide new examples of sub‐Riemannian manifolds with boundary equipped with a smooth measure that satisfy the RCD(K,N)$\mathsf {RCD}(K, N)$ condition. They are constructed by equipping the half‐plane, the hemisphere and the hyperbolic half‐plane with a two‐dimensional almost‐Riemannian structure and a measure that vanishes on their ...

Holography, probe branes and isoperimetric inequalities

Physics Letters B, 2015
In many instances of holographic correspondences between a d-dimensional boundary theory and a (d+1)-dimensional bulk, a direct argument in the boundary theory implies that there must exist a simple and precise relation between the Euclidean on-shell ...

Decorated phases in triblock copolymers: Zeroth‐ and first‐order analysis

Transactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.
Abstract We study a two‐dimensional inhibitory ternary system characterized by a free energy functional that combines an interface short‐range interaction energy promoting microdomain growth with a Coulomb‐type long‐range interaction energy that prevents microdomains from unlimited spreading.

Orlicz Mean Dual Affine Quermassintegrals

Journal of Function Spaces, 2018
Our main aim is to generalize the mean dual affine quermassintegrals to the Orlicz space. Under the framework of dual Orlicz-Brunn-Minkowski theory, we introduce a new affine geometric quantity by calculating the first Orlicz variation of the mean dual ...
