In this paper using differential operator, we introduce a certain subclass of multivalent analytic functions on the open unit disk. Such conditions are subordination and superordination to investigate some inclusion, convolution and inequality properties, distortion theorems and also sufficient conditions for multivalent starlikeness are discussed.

 

Keywords: Multivalent function, starlike function, subordination, superordination, differential operator.

In this work we introduce (Fuzzy Maximal Open Set) and (Fuzzy Minimal Open Set). We introduce these fuzzy set in a fuzzy topological spaces defined on a fuzzy set ̃ instead of crisp set . We studied some properties of these fuzzy sets and some interrelationships between them.
