On the Constructively Determination the Spectral Invariants of the Periodic Multidimensional Schrodinger Operator
O. A. Veliev
In this paper we constructively determine a family of the spectral invariants of the multidimensional Schrodinger operator with a periodic potential by the given band functions.
