Spontaneous branes formation
Arkadiy A. Popov, Sergey G. Rubin
This paper presents a study of brane formation in six-dimensional space. There is no a priori assumption of the brane(s) existence. However, the analysis of the generalized Einstei…
Cosmological models based on an asymmetric scalar doublet with kinetic coupling of components. II. Numerical modeling
Yu. G. Ignsat'ev, I. A. Kokh
Numerical modeling of a mathematical model of the cosmological evolution of an asymmetric scalar doublet with kinetic interaction between the components was carried out. A wide ran…
Symplectic geometry of electrical networks
Boris Bychkov, Vassily Gorbounov, Lazar Guterman +1
In this paper we relate a well-known in symplectic geometry compactification of the space of symmetric bilinear forms considered as a chart of the Lagrangian Grassmannian to the sp…
Comments on the article "M.O. Katanaev, Complete separation of variables in the geodesic Hamilton-Jacobi equation in four dimensions. Physica Scripta (2023), 98, 104001" by V. V. Obukhov, K. E. Osetrin, and A. V. Shapovalov
M. O. Katanaev
This is a detailed answer to the criticism of my paper.
Cosmological models based on an asymmetric scalar doublet with kinetic coupling of components. I. General properties of the cosmological model
Yu. G. Ignat'ev, I. A. Kokh
A mathematical model of the Universe evolution, based on asymmetric doublet of classical and phantom dcalar Higgs fields with a kinetic connection between the components, has been…
Primordial Black Holes from Spatially Varying Cosmological Constant Induced by Field Fluctuations in Extra Dimensions
Arkady A. Popov, Sergey G. Rubin, Alexander S. Sakharov
The origin and evolution of supermassive black holes (SMBHs) in our universe have sparked controversy. In this study, we explore the hypothesis that some of these black holes may h…
