| The purpose of this paper is to give some sufficient conditions on / and g for ensuring that all solutions or all bounded solutions of general second order functional differential equation 〔r(t)g(y′(t))〕′+ f(t,y(t),y(p(t)),y′(t),y′(q(t)))=0 are oscillatory, or it has at least one bounded nonoscillatory solution. |
