Four-dimensional Brane–Chern–Simons Gravity and Cosmology

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
From the field equations corresponding to a four-dimensional brane embedded in the five-dimensional spacetime of the Einstein–Chern–Simons theory for gravity, we find cosmological solutions that describe an accelerated expansion for a flat universe ...

Dynamical Analysis and Cosmological Evolution in Weyl Integrable Gravity

open access: yesUniverse, 2021
We investigate the cosmological evolution for the physical parameters in Weyl integrable gravity in a Friedmann–Lemaître–Robertson–Walker universe with zero spatial curvature.

Lifts of Symmetric Tensors: Fluids, Plasma, and Grad Hierarchy

open access: yesEntropy, 2019
Geometrical and algebraic aspects of the Hamiltonian realizations of the Euler’s fluid and the Vlasov’s plasma are investigated. A purely geometric pathway (involving complete lifts and vertical representatives) is proposed, which establishes

The Lie symmetry analysis and exact Jacobi elliptic solutions for the Kawahara–KdV type equations

open access: yesResults in Physics, 2021
In this article, we aim to employ two analytical methods including, the Lie symmetry method and the Jacobi elliptical solutions finder method to acquire exact solitary wave solutions in various forms of (1+1)-dimensional Kawahara–KdV type equation and ...

Geometric scaling as traveling waves [PDF]

open access: yes, 2003
We show the relevance of the nonlinear Fisher and Kolmogorov-Petrovsky- Piscounov (KPP) equation to the problem of high energy evolution of the QCD amplitudes. We explain how the traveling wave solutions of this equation are related to geometric scaling,

On the Bilinear Second Order Differential Realization of an Infinite-Dimensional Dynamical System: An Approach Based on Extensions to M2-Operators

open access: yesFractal and Fractional, 2023
Considering the case of a continual bundle of controlled dynamic processes, the authors have studied the functional-geometric conditions of existence of non-stationary coefficients-operators from the differential realization of this bundle in the class ...

Einstein-aether theory in Weyl integrable geometry

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We study the Einstein-aether theory in Weyl integrable geometry. The scalar field which defines the Weyl affine connection is introduced in the gravitational field equation.

Linear and nonlinear effects analysis on wave profiles in optics and quantum physics

open access: yesResults in Physics, 2021
In the field of quantum mechanics and fluid physics, especially in the study of nonlinear geometric optics and superconductivity, the Landau-Ginzburg-Higgs (LGH) and the (2 + 1)-dimensional Novikov-Veselov (NV) equations are two significant models.
