Description
Book SynopsisPresents an overview of the developments in the area of localization for quasi-periodic lattice Schrodinger operators and the theory of quasi-periodicity in Hamiltonian evolution equations. This book emphasises on so-called 'non-perturbative' methods and the role of subharmonic function theory and semi-algebraic set methods.
Trade Review"This text is an up to date introduction to localization problems for lattice Schrodinger operations with deterministic ergodic potentials by one of the leading experts... I can recommend it to any graduate student or researcher in the field."--G. Teschl, Monatschefte fur Mathematik
