| Abstract: | A Estimate is established for the distance between adjacent zeros of the solutions of nonlinear neutral dif- ferential equations with variable delays. By changing the differential equation with the related differential inequali- ty, the zero distribution of solutions of the nonlinear neutral differential equation with variable delays was consid- ered, and a lot of known results were generalized and improved. |
