Effects of f(R) Model on the Dynamical Instability of Expansionfree Gravitational Collapse
M. Sharif, H. Rizwana Kausar
Dark energy models based on f(R) theory have been extensively studied in literature to realize the late time acceleration. In this paper, we have chosen a viable f(R) model and dis…
Expansionfree Fluid Evolution and Skripkin Model in f(R) Theory
M. Sharif, H. Rizwana Kausar
We consider the modified theory of gravity whose higher order curvature terms are interpreted as a gravitational fluid or dark source. The gravitational collapse of a spheri…
Dust Static Spherically Symmetric Solution in Gravity
Muhammad Sharif, Hafiza Rizwana Kausar
In this paper, we take dust matter and investigate static spherically symmetric solution of the field equations in metric f(R) gravity. The solution is found with constant Ricci sc…
Anisotropic Fluid and Bianchi Type III Model in f(R) Gravity
M. Sharif, H. Rizwana Kausar
This paper is devoted to study the Bianchi type III model in the presence of anisotropic fluid in f(R) gravity. Exponential and power-law volumetric expansions are used to obtain e…
