Derivation of the kinetic wave equation for quadratic dispersive problems in the inhomogeneous setting

American Journal of Mathematics, 2021
: We examine the validity of the kinetic description of wave turbulence for a model quadratic equation. We focus on the space-inhomogeneous case, which had not been treated earlier; the space-homogeneous case is a simple variant.

Relativistic anisotropic model of strange star SAX J1808.4-3658 admitting quadratic equation of state

International Journal of Modern Physics A, 2019
In this paper, we study the behavior of static spherically symmetric relativistic model of the strange star SAX J1808.4-3658 by exploring a new exact solution for anisotropic matter distribution.

Aspects of nonflat FRW bouncing models with quadratic equation of state

International Journal of Modern Physics A, 2018
In this paper, we investigate the possibility of a nonsingular model of universe in the framework of general relativity in nonflat FRW geometries with quadratic equation of state and bulk viscosity.

Compact stars with quadratic equation of state

, 2015
We provide new exact solutions to the Einstein-Maxwell system of equations for matter configurations with anisotropy and charge. The spacetime is static and spherically symmetric. A quadratic equation of state is utilised for the matter distribution.
