Ayman Kachmar, Mikael Persson
2013 Arab Journal of Mathematical Sciences  
We establish equality between the essential spectrum of the Schro¨dinger operator with magnetic field in the exterior of a compact arbitrary dimensional domain and that of the operator defined in all the space, and discuss applications of this equality. .lb (A.
