Logarithmic Corrections to Bekenstein-Hawking Entropy and Their Cosmological Implications

Bulk-viscous five-dimensional Kaluza–Klein cosmology within non-conservative gravitational frameworks and its implications for early-universe dynamics

Rigidity of Free Boundary Surfaces via a Modified Charged Hawking Mass

We introduce a modified charged Hawking mass for free boundary surfaces in time-symmetric three-dimensional Einstein–Maxwell initial data sets with a cosmological constant, and we investigate the rigidity of free boundary minimal two-disks that locally maximize this mass in Riemannian three-manifolds for which R-2|E|2\...

Spherically symmetric vacuum solution in Freund–Nambu scalar–tensor gravity

We present an exact solution in Freund–Nambu scalar–tensor gravity that extends the Janis–Newman–Winnicour (JNW) naked-singularity spacetime. The metric retains the JNW form governed by parameter n, while a new parameter q deforms the profile of the massive scalar field φ.\documentclass[12pt]{minimal} \usepackage{amsma...

Linear Fluctuation of Interfaces in Glauber–Kawasaki Dynamics

In this article, we find a scaling limit of the space-time mass fluctuation field of Glauber + Kawasaki particle dynamics around its hydrodynamic mean curvature interface limit. Here, the Glauber rates are scaled by K=KN\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepa...
