The Periodic Multidimensional Schrodinger Operator, Part 2,
Asymptotic Formulae for Bloch Functions and Fermi Surfaces
(100K, LATeX 2e)
ABSTRACT. In this paper we obtain asymptotic formulas for Bloch function of periodic
Schrodinger operator $-\Delta +q(x),$ of arbitrary dimension, when
corresponding quasimomentum lies near a diffraction hyperplane, but far from
the intersection of the two diffraction hyperplanes. Moreover, we write
asymptotic formulas for Bloch function and Fermi survaces, when
corresponding quasimomentum lies far from the diffraction hyperplanes,
obtained in my previous papers in improved and enlarged form.
