Kinematic Self-Similar Heat Conducting and Charge Solutions
M. Sharif, Wajiha Javed
The objective of this paper is to study the plane symmetric kinematic self-similar heat conducting fluid and charge dust solutions of the Einstein field equations. These solutions…
Re-Scaling of Energy in the Stringy Charged Black Hole Solutions using Approximate Symmetries
M. Sharif, Saira Waheed
This paper is devoted to study the energy problem in general relativity using approximate Lie symmetry methods for differential equations. We evaluate second-order approximate symm…
Gravitational Collapse: Expanding and Collapsing Regions
M. Sharif, G. Abbas
We investigate the expanding and collapsing regions by taking two well-known spherically symmetric spacetimes. For this purpose, the general formalism is developed by using Israel…
Effects of f(R) Dark Energy on Dissipative Anisotropic Collapsing Fluid
M. Sharif, H. Rizwana Kausar
The purpose of this paper is to study the effects of dark energy on dynamics of the collapsing fluid within the framework of metric f(R) gravity. The fluid distribution is assumed…
Dynamics of Charged Plane Symmetric Gravitational Collapse
M. Sharif, Aisha Siddiqa
In this paper, we study dynamics of the charged plane symmetric gravitational collapse. For this purpose, we discuss non-adiabatic flow of a viscous fluid and deduce the results fo…
Effects of Electromagnetic Field on the Dynamics of Bianchi type Universe with Anisotropic Dark Energy
M. Sharif, M. Zubair
Spatially homogeneous and anisotropic Bianchi type cosmological models with cosmological constant are investigated in the presence of anisotropic dark energy. We examine the…
