In the present paper, we introduce generalized differential operator of functions which are analytic and P- univalent in the unit disk Also we use this operator to introduce new classes of suitably normalized strongly close-to-convex functions and strongly starlike univalent functions with positive coefficients. Also we study a differential subordination involving generalized differential operator in a sector. As special cases of our work, we derive some simple sufficient conditions for members of the class univalent functions to be strongly starlike and strongly convex functions. We shall need some lemmas to prove our main result. Further some applications of our results are obtained. |
