The spectral theory of Schrödinger operators, particularly those with
random potentials, continues to be a very active field of research. This
work focuses on various known criteria in the spectral theory of
selfadjoint operators. Concise unified presentation is aimed at graduate
students and researchers working in the spectral theory of Schrödinger
operators with either fixed or random potentials. However, given the
large gap that this book fills in the literature, it will serve a wider
audience of mathematical physicists in its contribution to works in
spectral theory.
