Abstract

In this paper we have considered generalized Emden-Fowler equation,\n\y''(t)+
sigma t^
gamma y^
beta(t)=0, ~~~~~~~~t
in ]0,1[\n subject to the following boundary conditions ny(0)=1,~y(1)=0;~~
amp;~~y(0)=1,~y'(1)=y(1), where \γ,\β\nand \σ are real numbers, \γ<-2, \β>1. We propsoed to solve the\nabove BVPs with the aid of Haar wavelet coupled with quasilinearization\napproach as well as Newton-Raphson approach. We have also considered the\nspecial case of Emden-Fowler equation (\σ=-1,\γ=\(-1)/(2) and\n\β=\(3)/(2)) which is popularly, known as Thomas-Fermi equation. We\nhave analysed different cases of generalised Emden-Fowler equation and compared\nour results with existing results in literature. We observe that small\nperturbations in initial guesses does not affect the the final solution\nsignificantly.\n
