Abstract In the present paper, we will incorporate three very useful aspects of astrophysics, generalized polytropes, Karmarkar condition and complexity factor to study compact objects. For this purpose a charged anisotropic fluid distribution is used under static spherical symmetry. We develop framework for class I Lane–Emden equations non-isothermal isothermal regimes. Generalized polytropic ...

The aim of the present study is to a new model based on nonlinear singular second order delay differential equation Lane–Emden type and numerically solved by using heuristic technique. Four different examples are presented designed artificial neural networks optimized global search, local search methods their hybrid combinations, respectively, named as genetic algorithm (GA), sequential quadrat...

The purpose of this study is to provide a mathematical construction based on the novel singular perturbed model second kind (NSPM-SK) using standard form Lane–Emden. Lane–Emden types models have abundant applications in astrophysics. inclusive features are provided perturbed, pantograph, point together and shape factor NSPM-SK. These become more complicated by these factors through artificial n...

In this research study, a novel computational algorithm for solving second-order singular functional differential equation as generalization of the well-known Lane–Emden and differential-difference equations is presented by using Bessel bases. This technique depends on transforming problem into system algebraic unknown coefficients are determined solution will be known. The method tested severa...
