Abstract
Asymptotic properties of solutions of the singular differential equation are described. Here, f is Lipschitz continuous on ℝ and has at least two zeros 0 and . The function p is continuous on [0, ) and has a positive continuous derivative on (0, ) and . Further conditions for f and p under which the equation has oscillatory solutions converging to 0 are given.
