يركز هذا البحث بشكل أساسي على دراسة معادلة تفاضلية غير خطية ذات شرط غير محلي ذي باراميتر واحد. يقدم تحليلنا براهين دقيقة لوجود الحلول و وحدانيتها. علاوة على ذلك، ندرس استقرار الحل من خلال فحص اعتماده المتصل على الشرط الإبتدائي و الباراميتر. نقدم مثالًا عدديًا باستخدام أدوات MATLAB للتحقق من صحة النتائج النظرية ولتوضيح العلاقة بين الحل الوحيد والشرط الإبتدائي والباراميتر.
