Russ. Math. Surv. 44, No. 2, 145-225 (1989); translation from Usp. Mat. Nauk 44, No. 2(266), 121-184 (1989).
A constructive approach to the study of Riemann surfaces of Bloch-type functions is presented. Abstract Bloch-solutions are given using series similar to perturbation ones and their convergence is proved. The spectral theory of finite-zone operators is developed. The completeness of the Bloch series is established. Particular applications are discussed in detail. Chapter 1: Spectral theory of the time dependent Schrödinger operator. Chapter 2: The periodic boundary value problem for the Kadomtsev-Petviashvili equations. Chapter 3: Spectral theory for one- level energy 2-D periodic Schrödinger operator.
