Subordination results for some subclasses of analytic functions
We introduce two classes of analytic functions related to conic domains, using a new linear multiplier Dziok-Srivastava operator

The Douady-Earle extension of quasihomographies
Quasihomography is a useful notion to represent a sense-preserving automorphism of the unit circle T which admits a quasiconformal extension to the unit disc. For K ≥ 1 let denote the family of all K-quasihomographies of T. With any we associate the Douady-Earle extension and give an explicit and asymptotically sharp estimate of the norm of the complex dilatation of .
