A Schwarz lemma and composition operators
|Title:||A Schwarz lemma and composition operators||Authors:||Mackey, Michael

This gives a Schwarz lemma for holomorphic maps of the domain.We specialise to the case of a bounded symmetric domain and obtain some applications. In particular, we give the connected components of the space of composition operators with symbol in a bounded symmetric domain. This generalises results for the space of composition operators on H∞(Δ) in  and for H∞(B) , B the unit ball of a Hilbert space or commutative C*-algebra in .||Type of material:||Journal Article||Publisher:||Springer||Copyright (published version):||2004 Birkhauser Verlag Basel/Switzerland||Keywords:||Banach space;Schwarz lemma;Holomorphic maps;Hilbert space||DOI:||10.1007/s00020-003-1240-1||Language:||en||Status of Item:||Peer reviewed|
