Linear operators in Hilbert space play a fundamental role in the formulation of quantum theory. This book offers a self-contained presentation of the most important tools and methods from Hilbert space theory, with particular focus on the spectral theory of self-adjoint operators. But it also goes further by describing some applications in quantum mechanics, in particular the analysis of Schrödinger operators and quantum scattering theory. The final two chapters are devoted to Mourre's conjugate operator method and some of its consequences for scattering theory. The text gives complete proofs and includes numerous exercises.
Based on a one-year course offered to advanced undergraduates, the text will be especially useful to students with some background in quantum mechanics, to whom it will provide a fundamental treatment of some of the basic ideas of applied Hilbert space theory; in addition, the book will prove invaluable to lecturers of basic and advanced quantum mechanics and to mathematical physicists in general, including those who work in spectral and scattering theory.

Inside an insulating vacuum chamber in a tunnel about 100 meters below the surface of the Franco-Swiss plain near Geneva, packets of protons whirl around the 27-km circumference of the Large Hadron Collider (LHC) at a speed close to that of light, colliding every 25 nanoseconds at four beam crossings.
Robot Programming by Demonstration (PbD) examines methods by which a robot learns new skills through human guidance. Also referred to as learning by imitation, tutelage or apprenticeship learning, PbD takes inspiration from the way humans learn new skills by imitation, thereby developing methods by which new skills can be transmitted to a robot.
Solidi cation is one of the oldest processes for producing complex shapes for applications ranging from art to industry, and it remains as one of the most important commercial processes for many materials. Since the 1980's, numerous fundamental developments in the understanding of solidi cation processes and microstructure formation have come from both analytical theories and the application of computational techniques using commonly available powerful computers.
