Oscillation Criteria for Second Order Nonlinear Dynamic Equations with p-Laplacian and Damping

This paper concerns the oscillation of solutions of the second order nonlinear dynamic equation with p-Laplacian and damping (r(t)φα(x△(t)))△ +p(t)φα(x△σ(t))  +q(t)f(xσ(t)) =0(r(t)φα(x△(t)))△ +p(t)φα(x△σ(t))  +q(t)f(xσ(t)) =0 on a time scale ⊤ which is unbounded above. Sign changes are allowed for the coefficient functions r, p and q. Several examples are given to illustrate the main results.
