The theory of slice regular functions over quaternions is the central subject of the present volume. This recent theory has expanded rapidly, producing a variet

This book presents a functional calculus for n-tuples of not necessarily commuting linear operators. In particular, a functional calculus for quaternionic linea

The subject of this monograph is the quaternionic spectral theory based on the notion of S-spectrum. With the purpose of giving a systematic and self-contained
