Abstract AR
يهدف هذا البحث إلى تسليط الضوء على نتائج كلاسيكية و تقديم مبرهنات جديدة حول وجود و تمديد الحلول لتشمل مسألة كوشي غير الخطية التالية : {█(u^n (x)=f(x,u(x) ),0
نعتبر في البداية الحالة النموذجية للمعادلات الذاتية و بعد ذلك نقدم نبذة عن النتائج الكلاسيكية.
و نعير أهمية خاصة للحالات التي يكون فيها f من الشكل f (x) = q (x) ѱ (u) أو f (x) = h (x, u) + g (x,u) حيث تهمين على h دوال متزايدة بالنسبة u في حين نعتبر g شبيها بالتقلص.
و في البرهان على النتائج الجديدة الخاصة بالوجود, نستخدم طرق تعتمد على متناوبة شودر ذات النمط الخطي و نظرية النقطة الصامدة لكراسنوسلسكي.
و نوضح هذه النتائج بعدة أمثلة و أمثلة مضادة f : [0, T] XR → R.
Abstract EN
The aim of this paper is to review some classical results and present new theorems of existence and extendability of solutions to the following second-order nonlinear Cauchy problem : where f : [0, T] × R → R is continuous, derivative independent and T > 0, u0, u1 are real numbers.
We first consider the model case of autonomous equations and some classical results are surveyed.
Particular attention is then paid to the cases where f has either the form f (x, u) = q (x)ψ(u) or f (x, u) = h(x, u) + g (x, u) where ψ is nondecreasing, h is dominated by nondecreasing functions in u while g looks like a contraction in the second argument.
Methods based on the Leray-Schauder nonlinear alternative and the Krasnosel skii fixed point the Orem are used to prove new existence theorems.
Several examples and counterexamples illustrate the obtained results.
