A new functional calculus for noncommuting operators

open access: yesJournal 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 ...

Bicomplex holomorphic functional calculus [PDF]

open access: yesMathematische 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.

The Functional Calculus

Journal of the London Mathematical Society, 1995
The formula of Helffer and Sjöstrand for functions \(f(H)\) of a selfadjoint operator \(H\) is generalized and put into the real perspective. The author constructs a functional calculus for Banach space operators with real spectra and slowly increasing resolvents when approaching the spectrum.
