| Abstract: | The oscillation for a certain class of second‐order nonlinear neutral delay dynamic equations on time scales was discussed .Based on the time scales theory and some necessary analytic techniques ,and generalized Riccati transformation and the method of H function , some new sufficient conditions for the oscillation of the equations were obtained .Our results could improve the restriction of the conditions for the equation .Some existing results in the literature were improved and extended . Some examples were given to illustrate the importance of our results . |
