Bicomplex Holomorphic Functional Calculus [PDF]

Mathematische Nachrichten, 2014
In this paper we introduce and study a functional calculus for bicomplex linear bounded operators. The study is based on the decomposition of bicomplex numbers and of linear operators using the two nonreal idempotents.

Functional Calculus Estimates for Tadmor–Ritt Operators [PDF]

Journal of Mathematical Analysis and Applications, 2016
We show H∞-functional calculus estimates for Tadmor-Ritt operators (also known as Ritt operators), which generalize and improve results by Vitse. These estimates are in conformity with the best known power-bounds for Tadmor-Ritt operators in terms of the

A New Functional Calculus for Noncommuting Operators [PDF]

Journal of Functional Analysis, 2008
. In this paper we use the notion of slice monogenic functions introduced in a paper by Colombo, Sabadini and Struppa (see Israel J. Math. 2009) to define a new functional calculus for an n-tuple T=(T_1,..., T_n) of not necessarily commuting operators ...

Noncommutative Functional Calculus [PDF]

Progress in Mathematics, 2011
The book contains recent results concerning a functional calulus for n-tuples of not necessarily commuting linear operators and for quaternionic linear operators. These calculi are based on a new theory of hyperholomorphicity for functions with values in
