Differential equations with several non-monotone arguments: An oscillation result. (June 2017) - Chatzarakis, G.E.
Abstract: This paper is concerned with the oscillatory behavior of first-order differential equations with several non-monotone delay arguments and non-negative coefficients. A sufficient condition, involving lim sup, which guarantees the oscillation of all solutions is established. Also, an example illustrating the significance of the result is given.
