چکیده
The present paper deals with notions from the field of complex analysis which have been adapted to fuzzy sets theory, namely, part dealing geometric function theory. Several differential subordinations are established regarding operator L?m, given by L?m:An?An, L?mf(z)=(1??)Rmf(z)+?Smf(z), where An={f?H(U),f(z)=z+an+1zn+1+…,z?U} is subclass normalized holomorphic functions and operators Rmf(z) Smf(z) Ruscheweyh S?l?gean operator, respectively. Using a certain class analytic denoted SLFm?,? defined in open unit disc. Interesting results related this obtained using concept subordination. Examples also for pointing out applications theoretical contained original theorems corollaries.

A Note on Special Strong Differential Subordinations Using a New Multiplier Transformation and Ruscheweyh Derivative
In this paper we establish several strong differential subordinations regarding an extended new operator obtained as a linear combination of an extended Ruscheweyh derivative and an extended new multiplier transformation. A number of interesting consequences of these strong subordination results are discussed.

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

متن کاملA new characterization for Meir-Keeler condensing operators and its applications
Darbo's fixed point theorem and its generalizations play a crucial role in the existence of solutions in integral equations. Meir-Keeler condensing operators is a generalization of Darbo's fixed point theorem and most of other generalizations are a special case of this result. In recent years, some authors applied these generalizations to solve several special integral equations and some of the...
متن کاملDifferential Subordinations for Fractional- Linear Transformations
We establish that the differential subordinations of the forms p(z)+γzp′(z)≺ h(A1,B1;z) or p(z)+γzp′(z)/p(z) ≺ h(A2,B2;z) implies p(z) ≺ h(A,B;z), where γ ≥ 0 and h(A,B;z)= (1+Az)/(1+Bz) with −1≤ B <A.
