Oscillation results for fourth-order nonlinear dynamic equations. (English) Zbl 1260.34168
From the introduction: This work is concerned with oscillation of a fourth-order nonlinear dynamic equation $(px^{\Delta^3})^\Delta(t)+ q(t) f(x(\sigma(t)))= 0$ on an arbitrary time scale $$\mathbb{T}$$ with $$\sup\mathbb{T}=\infty$$.
