Some oscillation results for second-order nonlinear delay dynamic equations

We obtain some oscillation theorems for linear delay dynamic equations on a time scale. We illustrate the results by a number of examples. 1. Preliminary Results Consider the second order linear delay dynamic equation (1.1) L[x](t) := (r(t)x(t)) + n ∑ i=1 qi(t)x(τi(t)) = 0. We will be interested in obtaining oscillation theorems for (1.1) by comparing the solutions to a related equation without...

Oscillation criteria for second-order nonlinear neutral delay dynamic equations

In this paper we will establish some oscillation criteria for the second-order nonlinear neutral delay dynamic equation ( r(t) (( y(t)+ p(t)y(t − τ))∆)γ )∆ + f (t, y(t − δ))= 0 on a time scale T; here γ > 0 is a quotient of odd positive integers with r(t) and p(t) real-valued positive functions defined on T. To the best of our knowledge nothing is known regarding the qualitative behavior of the...

Oscillation of Second Order Delay Dynamic Equations

In this paper we establish some sufficient conditions for oscillation of second order delay dynamic equations on time scales. Our results not only unify the oscillation of second order delay differential and difference equations but also are new for q-difference equations and can be applied on any time scale. We illustrate our results with many examples.
