السلوك المقارب لحلول معادلات تفاضلية غير خطية من المرتبة الثالثة

Abstract EN

We study the asymptotic behavior of solutions of a nonlinear differential equation of the form: u’’’+ f(t[ uu'iu'-) = 0 ,f > 1 Using Bihari’s integral inequality, we obtain sufficient conditions for all of continuable solutions to be asymptotic to at2 + bt + c as t→∞ , Where a, b and c are real constants and n ≠ 0.
