New general integral operator
For ?i,?i ? i , ? i positive real numbers for all i=1,,n i = 1 ,  , n , we introduce a new integral operator of analytic functions I ? i , ? i ( f 1 ,  , f n ) ( z ) defined by I ? i , ? i ( f 1 ,  , f n ) ( z ) = ? 0 z ? i = 1 n ( f i ? ( t ) ) ? i ( f i ( t ) t ) ? i d t . In this paper, we obtain sufficient conditions for this operator to be in the class N(?) N ( ? ) . Furthermore, we determine the order of convexity of I ? i , ? i ( f 1 ,  , f n ) ( z ) .
