Abstract:

In this paper, we investigate the oscillation of bounded solutions of second-order nonlinear neutral delay dynamic equation with oscillating coefficients of the form
(r(t)([y(t)+p(t)y(τ(t))]Δ)α)Δ+f(t, y(δ(t)))=0
on an arbitrary time scale T, where p is an oscillating function defined on T and α>0 is a quotient of odd positive integers. We get some sufficient conditions for the oscillation of all bounded solutions of the equation by developing a Riccati transformation technique. The obtained results extend and complement some known results in which p(t)≥0 for tT is required. Several examples are presented to illustrate our main results.

Key words: Bounded oscillation, Second-order nonlinear neutral delay dynamic equation, Oscillating coefficient, Time scale, Riccati transformation
