Cullen-regular quaternionic functions in a Fueter operator framework
arXiv:0805.0141
Abstract
We show characterizations of the class of Cullen-regular functions in the sense of Gentili-Struppa for any domain in terms of the Fueter operator. We then state a Integral Theorem and discuss how it can be used to define a more general version of Cullen-regularity, that does not require the function to be of class .
