Oscillatory properties of solutions of certain nth order functional differential equations

Gary Grefsrud

Vol. 60 (1975), No. 2, 83–93
Abstract

With n even and tn1a(t)dt < , necessary conditions for x(n)(t) + a(t)f(x(g(t))) = 0 to have a bounded nonoscillatory solution are given. If n = 2, sufficient conditions are also given. Conditions which insure that solutions of x(n)(t) + f(t,x(g(t))) = 0 are oscillatory or tend monotonically to zero are also presented in this paper.
