Название: Perturbation Theory for the Schrödinger Operator with a Periodic Potential (Lecture Notes in Mathematics, 1663)
Автор: Karpeshina Y. E.
Аннотация:
The main aim of this book is to construct perturbation formulae for Bloch eigenvalues and their spectral projections in a high energy region on a rich set of quasimomenta. The construction of these formulae is connected with the investigation of a complicated picture of the crystal diffraction.
