New results for the upper bounds of the distance between adjacent zeros of first-order differential equations with several variable delays

Abstract The distance between consecutive zeros of a first-order differential equation with several variable delays is studied. Here, we show that the distribution of zeros of differential equations with variable delays is not an easy extension of the case of constant delays. We obtain new upper bou...
