Generalized adjoints and applications to composition operators

Functional Analysis 2018-11-01 v1

Abstract

We generalize the classical notion of adjoint of a linear operator and the Aron-Schottenloher notion of adjoint of a homogeneous polynomial. The general notion is shown to enjoy several properties enjoyed by the classical ones, nevertheless differences between the two theories are detected. The proofs of both positive and negative results are not simple adaptations of the linear cases, actually nonlinear arguments are often required. Applications of the generalized adjoints to Lindstr\"om-Schl\"uchtermann type theorems for composition operators are provided.
