"This book presents reviews of some recent topics in the theory of Schrodinger operators. It includes a short introduction to the subject, a survey of the theory of the Schrodinger equation when the potential depends on the time periodically, an introduction to the so-called FBI transformation (also known as coherent state expansion) with application to the semi-classical limit of the S-matrix, an overview of inverse spectral and scattering problems, and a study of the ground state of the Pauli-Fierz model with the use of the functional integral. The material is accessible to graduate students and non-expert researchers."--BOOK JACKET.
