Oscillation and asymptotic behavior of a third-order nonlinear dynamic equation. (English) Zbl 1145.34329
Summary: We establish some new oscillation criteria for the third-order nonlinear dynamic equation
$(c(t)((a(t)x^\Delta)^\gamma)^\Delta +f(t,x(t))=0,\quad t\in[a,\infty)_{\mathbb T}$
on time scales, where $$\gamma\geq 1$$ is a quotient of odd integers. Our results not only unify the oscillation theory for third-order nonlinear differential and difference equations but also are new for the $$q$$-difference equations and can be applied on different time scales. The results improve some of the main results in the literature in the case when $$f = 1$$.
