Abstract AR
في هذا البحث تمت دراسة المعادلات التباطؤية الخطية ذات المعاملات الموجبة و السالبة من الرتبة الأولى؟ حيث تم إيجاد شروط ضرورية و كافية لضمان تذبذب كافة حلول المعادلة x(t) P (t) x ((t)) - Q(t) x((t)) 0, و شروط كافية أخرى للحلول غير المتذبذبة كي تكون متقاربة إلى الصفر، و قد أعطينا الأمثلة لتوضيح هذه النتائج.
Abstract EN
Oscillation criteria are obtained for all solutions of the first-order linear delay differential equations with positive and negative coefficients where we established some sufficient conditions so that every solution of (1.1) oscillates.
This paper generalized the results in [11].
Some examples are considered to illustrate our main results.
