Abstract

In this paper, we are concerned with the oscillation of the second-order half-linear dynamic equation
\[
\Big(a(t)|x^\Delta(t)|^{\gamma-1}x^\Delta (t)\Big)^\Delta+q(t)|x(t)|^{\gamma-1}x(t)=0
\]
on an arbitrary time scale $\mathbb{T}$, where $\gamma>0$ is a constant. By using a generalized Riccati substitution, the P\"{o}tzsche chain rule and a Hardy-Littlewood-P\'{o}lya inequality, we obtain some sufficient conditions for the oscillation of the equation and improve and extend some known results in which $\gamma>0$ is a quotient of odd positive integers. We also give some examples to illustrate our main results.
