Stability of an additive-quadratic functional equation in modular spaces

Open Mathematics
Using the direct method, we prove the Hyers-Ulam-Rassias stability of the following functional equation: ϕ(x+y,z+w)+ϕ(x−y,z−w)−2ϕ(x,z)−2ϕ(x,w)=0\phi \left(x+y,z+w)+\phi \left(x-y,z-w)-2\phi \left(x,z)-2\phi \left(x,w)=0 in ρ\rho -complete convex modular ...

A visualization of null geodesics for the bonnor massive dipole

Revista de Matemática: Teoría y Aplicaciones, 2015
In this work we simulate null geodesics for the Bonnor massive dipole metric by implementing a symbolic-numerical algorithm in Sage and Python. This program is also capable of visualizing in 3D, in principle, the geodesics for any given metric. Geodesics

Liquid crystal director fields in three-dimensional non-Euclidean geometries

New Journal of Physics, 2020
This paper investigates nematic liquid crystals in three-dimensional curved space, and determines which director deformation modes are compatible with each possible type of non-Euclidean geometry. Previous work by Sethna et al showed that double twist is

Physics-to-Geometry Transformation to Construct Identities between Reynolds Stresses

Mathematics, 2023
Modeling has become firmly established as a methodology to close the Reynolds-averaged Navier–Stokes (RANS) equations, owing to theoretical and empirical efforts towards a complete formulation of the Reynolds stress tensor and, recently, breakthroughs in

Infinitesimal Differential Geometry

, 2003
Submitted to: AMUC, December 2003. We added a sheaf property to the definition of $C^n$ space so that now they generalize diffeological spaces and every extended space has now a topology. We also added a final section which compares our construction with other theories of infinitesimals like NSA, SDG and Weil ...
