Complex Dynamics of the family

The aim of this work is to study the complex dynamics of the family F={,}, of transcendental meromorphic functions. We prove that certain intervals are contained in J(f) or in F(f ) and we prove that Julia set containsand show that Fatou set of the functions in F contains certain components for different values of. We characterize Julia set of , for different values of, as the closure of the escaping points, and use this characterization to give computer images for these sets.
