Complexity Issues in Computing Spectra, Pseudospectra and Resolvents
Anders C. Hansen, Olavi Nevanlinna
We display methods that allow for computations of spectra, pseudospectra and resolvents of linear operators on Hilbert spaces and also elements in unital Banach algebras. The paper…

Multicentric calculus and the Riesz projection
Diana Apetrei, Olavi Nevanlinna
In multicentric holomorphic calculus one represents the function using a new polynomial variable in such a way that when it is evaluated at the operator then $p(A…
