We obtained some geometric properties, such as the coefficient estimates, convex combination, extreme points, and convolution (Hadamard product), which are required. لاودلا نم ةئف اهميمعتو يلضافت لماع ةطساهب ةفرعملا ؤفاكتلا ةيداحا ةيقفاهتلا يبنلادبع رخاف نتاف * مساج ديمحلا دبع مساق ، قا رعلا ،دادغب ،دادغب ةعماج ،مهلعلا ةيلك ،تايضايرلا مدق هصلاخلا ضعب ققحن و يلضافتلا رثؤملا اهددحي يتلا ؤفاكتلا ةيداحا لاودلا نم ةديدج ةئف ثحبلا اذه يف فافتللااو ةيجراخلا طاقنلا,بدحملا عمجلا,لماعملا تا ريدقت لتم ةيسدنهلا صاهخلا
