Abstract: | This is a continuation of our work (González-Cervantes et al. in On the Bergman theory for solenoidal and irrotational vector
fields. I. General theory. Operator theory: advances and applications. Birkhauser, accepted) where for solenoidal and irrotational
vector fields theory as well as for the Moisil–Théodoresco quaternionic analysis we introduced the notions of the Bergman
space and the Bergman reproducing kernel and studied their main properties. In particular, we described the behavior of the
Bergman theory for a given domain whenever the domain is transformed by a conformal map. The formulas obtained hint that the
corresponding objects (spaces, operators, etc.) can be characterized as conformally covariant or invariant, and in the present
paper we construct a series of categories and functors which allow us to give such characterizations in precise terms. |
