Continuity of the spectra for families of magnetic operators on $$\mathbb Z^d$$ Z d

Continuity of the spectra for families of magnetic operators on $$\mathbb Z^d$$ Z d For families of magnetic self-adjoint operators on $$\mathbb Z^d$$ Z d whose symbols and magnetic fields depend continuously on a parameter $$\epsilon $$ ϵ , it is shown that the spectrum of these operators also varies continuously with respect to $$\epsilon $$ ϵ . The proof is based on an algebraic setting involving twisted crossed product $$C^*$$ C ∗ -algebras. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Analysis and Mathematical Physics Springer Journals

Abstract

For families of magnetic self-adjoint operators on $$\mathbb Z^d$$ Z d whose symbols and magnetic fields depend continuously on a parameter $$\epsilon $$ ϵ , it is shown that the spectrum of these operators also varies continuously with respect to $$\epsilon $$ ϵ . The proof is based on an algebraic setting involving twisted crossed product $$C^*$$ C ∗ -algebras.
