摘要（Abstract） 

We describe a multiscale selfsimilar struture of solutions to one of the most popular models of the almost periodic operator theory, the difference Schroedinger equation with a potential of the form  a ctg(b n+c), where  a, b and c are constants, and n is an integer variable. The talk is based on a joint work with F.Klopp.
Research interests: Asymptotic methods of mathematical physics (quasi-classical, short-wave and adiabatic asymptotics); Spectral theory of ergodic Schr\»odinger operators; Analytic theory of difference equations on the complex plane.
