The $H^{\infty}$ functional calculus based on the $S$ -spectrum for quaternionic operators and for $n$ -tuples of noncommuting operators

D. Alpay, F. Colombo, T. Qian +1

In this paper we extend the $H^{\infty}$ functional calculus to quaternionic operators and to $n$ -tuples of noncommuting operators using the theory of slice hyperholomorphic function…

Beurling-Lax type theorems in the complex and quaternionic setting: the half-space case

Daniel Alpay, Irene Sabadini

We give a generalization of the Beurling-Lax theorem both in the complex and quaternionic settings. We consider in the first case functions meromorphic in the right complex half-pl…
