This volume deals with those topics of mathematical physics, associated with the study of the Schrodinger equation, which are considered to be the most important. Chapter 1 presents the basic concepts of quantum mechanics. Chapter 2 provides an introduction to the spectral theory of the one-dimensional Schrodinger equation. Chapter 3 opens with a discussion of the spectral theory of the multi-dimensional Schrodinger equation, which is a far more complex case and requires careful consideration of aspects which are trivial in the one-dimensional case. Chapter 4 presents the scattering theory...
