Spectrum of composition operators on spaces of holomorphic functions
Let D be the open unit disk of C and u of D in D a holomorphic function. Let H (D) denote the space of holomorphic functions over C. The objective of the talk is to present the properties of the composition operator defined by Cu (f) = crazy. The presentation will in particular be dedicated to the characterization of the point spectrum and the Cu spectrum. The results presented in this talk were obtained in collaboration with Wolfgang Arendt and Isabelle Chalendar.
