Abstract: Our purpose is to analyze a first order nonlinear differential equation with advanced arguments. Then, some sufficient conditions for the oscillatory solutions of this equation are presented. Our results essentially improve two conditions in the paper ``Oscillation tests for nonlinear differential equations with several nonmonotone advanced arguments'' by N. Kil\iç, Ö. Öcalan and U. M. Özkan. Also we give an example to illustrate our results.
Keywords: nonlinear advanced equation; nonmonotone argument; oscillatory solution
