Title: Oscillatory behavior of solutions to third-order nonlinear differential equations with a superlinear neutral term Authors: Ercan Tunc (Gaziosmanpasa Univ.,Tokat, Turkey) Said R. Grace (Cairo Univ., Orman, Giza, Egypt) Abstract: This article studies the oscillatory and asymptotic behavior of solutions to a class of third-order nonlinear differential equations with superlinear neutral term. The results are obtained by a comparison with first-order delay differential equations whose oscillatory behavior is known, and by using integral criteria. Two examples are provided to illustrate the results. Submitted March 3, 2020. Published April 13, 2020. Math Subject Classifications: 34C10, 34K11, 34K40.
