Oscillation criteria for a forced second-order nonlinear dynamic equation. (English)
[J] J. Difference Equ. Appl. 14, No. 10-11, 997-1009 (2008). ISSN 1023-6198

By means of a Riccati technique and the function class $\{u\in C^1_{rd}({\Bbb{T}}): u(t)\not\equiv 0$ on $[a, b]$, $u(a)=u(b)=0\}$, the authors establish new interval oscillation criteria for forced second-order nonlinear dynamic equations on time scales of the form $$\left(p(t)x^{\Delta}(t)\right)^{\Delta}+q(t)\vert x^\sigma(t)\vert ^\gamma \text {sgn}\,x^\sigma(t)=f(t),\quad t\in \Bbb{T},$$ where ${\Bbb{T}}$ is a time scale and $\gamma\ge 1$ is a constant. Four interesting examples are included to show the significance of the results.
