On The Solvability Complexity Index for Unbounded Selfadjoint and Schrödinger Operators

Abstract

We study the Solvability Complexity Index (SCI) for the spectral problem of unbounded selfadjoint operators on separable Hilbert spaces and perturbations thereof. In particular, we show that if the extended essential spectrum of a selfadjoint operator is convex, then the SCI for computing its spectrum is equal to 1. This result is then extended to relatively compact perturbations of such operators and applied to Schrödinger operators with (complex valued) potentials decaying at infinity to obtain SCI=1 in this case, as well.

Seminars in this series are organised by Dr Marina Iliopoulou and Dr Mark Roelands.
