| Abstract: | The purpose of this paper is to study the distribution of zerose of solutions of the neutral delay differential equations. An estimate is established forthe distance between adjacent zeroes of the solutions of such equations underless restrictive hypotheses on the variable table coefficients. The results obtainedimprove and extend some known results in the literature. |
