In this paper ,we improve the results of the existence of fixed point theory for generalized quasi contraction maps in modular metric spaces which extends the results of Y.Cho.et al,[Quasi-contraction mapping in modular metric

Abstract. In the present paper we study quasi-subordination under a multivalent function and we consider a certain subclass of (normalized) analytic functions based on quasi-subordination. Applications and consequences of the main results are also cosidered which some of them extend the earlier issues.Mathematics Subject Classification (2010): 30C45, 30C80.
