Abstract

Mathematics Mathematics, Applied Physical Sciences Science & Technology
The oscillation of a first order differential equation with several non-monotone delays is studied. A standard technique is improved and used to prove some new oscillation criteria of lim sup type. The applicability and strength of the obtained results are assured using an analytic approach as well as a practical example.
