M-hyponormality in several variables operator theory
Abstract
In recent years, the study of bounded linear operators in several variables has received
great interest from many authors, including the second author’s previous
contributions. In our present work, we define a new class of multivariable operator
theory, which we have called M-hyponormal tuple. We present some algebraic and
spectral properties associated with them.
