On the convergence of a fourth-order method for a class of singular boundary value problems

In the present paper we extend the fourth order method developed by Chawla et al. [M.M. Chawla, R. Subramanian, H.L. Sathi, A fourth order method for a singular two-point boundary value problem, BIT 28 (1988) 88–97] to a class of singular boundary value problems (p(x)y′)′=p(x)f(x,y),0
