New results on oscillation for delay differential equations with piecewise constant argument. (English) Zbl 1065.34061
This paper deals with the oscillatory behavior of solutions of first-order delay differential equations with oscillating coefficients and piecewise constant arguments. Examples are included to illustrate the importance of the results. Also see J. H. Shen and I. P. Stavroulakis [J. Math. Anal. Appl. 248, 385–401 (2000; Zbl 0966.34063)] and the authors [Tamkang J. Math. 32, 293–304 (2001; Zbl 1004.34056)].
