Abstract AR
تناولنا في هذا البحث نظام حصاد الفريسة و المفترس و الذي يتضمن مرض في الفريسة.
وجود، و وحدانية و قد الحيل للنظام نوقشة.
تحليل الاستقرارية لجميع النقاط الثابتة الممكنة للنظام درس.
شروط الإصرار للنظام وجدت.
بمحاكاة سلوك النظام عدد من مخططات التفرع رسمت و لقيم معالم مختلفة.
بينت النتائج بأن وجود المرض و الحصاد في النظام يؤدي إلى وجود جواذب مختلفة بضمنها الفوضى.
Abstract EN
In this paper, a harvested prey-predator model involving infectious disease in prey is considered.
The existence, uniqueness and boundedness of the solution are discussed.
The stability analysis of all possible equilibrium points are carried out.
The persistence conditions of the system are established.
The behavior of the system is simulated and bifurcation diagrams are obtained for different parameters.
The results show that the existence of disease and harvesting can give rise to multiple attractors, including chaos, with variations in critical parameters.
