Oscillation of second-order nonlinear neutral dynamic equations on time scales

This paper is concerned with the oscillation of second-order nonlinear neutral dynamic equations of the form(r(t)((y(t)+p(t)y(τ(t)))Δ)γ)Δ+f(t,y(δ(t)))=0,r(t)(y(t)+p(t)y(τ(t)))ΔγΔ+f(t,y(δ(t)))=0,on a time scale TT. By using a generalized Riccati technique and integral averaging techniques, we establish new oscillation results which handle some cases not covered by known criteria.
