  Article:   DOMINANTS AND BEST DOMINANTS IN FUZZY DIFFERENTIAL SUBORDINATIONS.

Authors:  GEORGIA IRINA OROS, GHEORGHE OROS.
 
       
         
  Abstract:  

The theory of differential subordination was introduced by S.S. Miller and P.T. Mocanu in [1] and [2] then developed in many other papers. Using the notion of differential subordination, in [5] the authors define the notion of fuzzy subordination and in [6] they define the notion of fuzzy differential subordination.In this paper, we determine conditions for a function to be a dominant of the fuzzy differential subordination and we also give the best dominant.
