On one formulation of the Green function method for periodic lattices (English)
0 references
The authors are motivated by the study of energy spectrum of crystal solids in terms of the Schrödinger equation. They propose a modification of the Green function method which makes it possible (i) to replace integration over the cell of the crystal body by integration over the whole space and (ii) to improve the rate of convergence of the corresponding series.
