هذا البحث سيدرس شروط استقراريه الحل الصفري في الحالة شبه الخطية لمعادلة تفاضلية من الرتبة الثالثة بالشكل : ym+ p1(t) ym+ p2 (t)y′+ p3 (t) y = h(t, y, y, y) حيث أن Ps= πs [qs=ws (t)], qs ∈ c, ws(t) : Δ →c, s=1,2,3 t ∈Δ=[a, ∞], a ∈ n ان المعادلة المميزة للمعادلة التفاضلية أعلاه لها زوج من الجذور المعقدة بالشكل : 0 , λ > 1 2 0 λ = −λ = iλ و الجذر الأخر يحقق الخاصية Reλ3 < −M,M >0
Abstract EN
In this paper, we study the conditions under which the zero solution is stable in the semi- liner case for certain third order differential equation of the form : ( ) ( ) ( ) ( , , , ) 1 2 3 y′′′ + p t y′′ + p t y′ + p t y = h t y y′ y′′ Where w t C , s = 1,2,3 s q C , ( ) : → s p [q w (t )] , ∈ s s s s = π + t ∈ = [a,∞) , a ∈ N The characteristic equation of the above differential equation has complex roots of the form : 0 and the other root has the following 0 , λ > 1 2 0 λ = −λ = iλ Re, 0 .
