| Abstract: | In the paper,the oscillation for a class of second-order nonlinear neutral delay dynamic equation on time scales was discussed.First,the sufficient condition for oscillation of the equation was proposed by introducing the generalized Riccati transformation and the time scales theory.Second,a non-oscillation criterion that the equation has bounded eventually positive solutions was obtained by using the fixed point theorem in Banach space and some analysis techniques.These results are new and they unify and generalize some corresponding known results in this field. |
