The present paper reports a study on neutron stars in the f(R) gravity framework for Hu–Sawicki model, Starobinsky Tsujikawa and Exponential Gravity model. First, we have used TOV equation framework, where obtained two higher order differential equations λ ψ, with both functions depending radial coordinate. Furthermore, considered BD theory, which is an equivalent theory of gravity, introduced ...

‎In this paper‎, ‎we obtain exact solutions involving parameters of some nonlinear PDEs in mathmatical physics; namely the one-‎dimensional modified complex Ginzburg-Landau equation by using the $ (G'/G) $ expansion method‎, homogeneous balance method, extended F-expansion method‎. ‎By ‎using homogeneous balance principle and the extended F-expansion, more periodic wave solutions expressed by j...
