The superadiabatic projectors method applied to the spectral theory of magnetic operators
Lino Benedetto, Clotilde Fermanian Kammerer, Nicolas Raymond +1
This article deals with a generalization of the superadiabatic projectors method. In a general framework, the well-known superadiabatic projectors are constructed and accurately de…
