On the oscillation of third order functional differential equations (Q1011894)

This paper presents some new criteria for oscillatory behavior of solutions of third order functional differential equations of the form \[ (a(t)(x'(t))^\alpha))''+q(t)f(x[g(t)])=0 \] and \[ (a(t)(x'(t))^\alpha))''=q(t)f(x[g(t)])+p(t)h(x[\sigma(t)]), \] where \(\int^\infty a^{-1\alpha}(s)ds<\infty.\)
