Halbgruppen und komplexe Dynamik
Investigating semigroups holomorphic dynamics by considering semigroups of mappings together with constants, we first discuss a method to construct multplicative characters and then to describe the automorphism group of different semigroups connected with holomorphic dynamics. We give examples showing that the representation theory of this kind of semigroups is relevant to holomorphic dynamics. This is joint work with C.Cabrera and P.Makienko at UNAM, Mexico.
