Rainbow McVittie Horizons in an Expanding Universe
Amani Ashour, Ahmed Farag Ali
We derive the Friedmann dynamics and apparent-horizon thermodynamics of a spatially flat McVittie spacetime in Gravity's Rainbow and construct a consistent non-accreting perfect-fl…
Golden and Metallic Structures on Hessian Manifolds
Jonathan Washburn, Milan ZlatanoviÄ
The paper studies a degenerate Hessian geometry arising from a reciprocal cost function and introduces a family of nondegenerate Hessian metrics to build a (1,1)-tensor whose trace…
Multidimensional cost geometry
Jonathan Washburn, Milan ZlatanoviÄ, Philip Beltracchi
In this paper, we study the geometric structure induced by the canonical reciprocal cost function and its natural -dimensional extension. In logarithmic coordinates, the potenti…
Einstein connection of nonsymmetric pseudo-Riemannian manifold, II
Vladimir Rovenski, Milan ZlatanoviÄ, Miroslav MaksimoviÄ
Advances in modern physics since Einstein have made the nonsymmetric metric (0,2)-tensor , where is a pseudo-Riemannian metric associated with gravity, and is a…
The d'Alembert Inevitability Theorem
Jonathan Washburn, Milan ZlatanoviÄ, Elshad Allahyarov
We study functions satisfying the composition law with a symmetric polynomial combiner . We prove that symmetry together with a quadratic degree boun…
