| dc.description.abstract | جبرةـ Abstract : The objective of this memory is the qualitative study of a class of polynomial planar differential systems. The results obtained in this study concern the existence and the number of periodic solutions isolated by consequent limit cycles. And we have shown we have shown that it has at most two limit cycles. Moreover, we were able to determine the explicit expressions of the limit cycles (algebraic and non-algebraic) found for the studied class. Finally, some examples were presented to illustrat الهدف من هذه المذرة هو الدراسة النوعة لصنف من الانظمة التفاضلة ثیرات الحدود المستوةـ النتائج التي تحصلنا علیها في هذه الدراسة تهتم بوجود و عدد الحلول الدورة المعزولة التالي دورات الحدـ و قد اثبتنا انها تحتو على دورتین حدیتین على الاكثرـ الإضافة الى ذلك تمننا من تحدید التغییرات الصرحة لهذه الدورات الحدة (جبرة و غیر جبرة) النسة لهذه الفئة المدروسة اخیراـ قدمنا عض الامثلة لتوضح النتائج التي | en_US |
