Quantum Mechanics

Intended for beginning graduate students, this text takes the reader f rom the familiar coordinate representation of quantum mechanics to the modern algebraic approach, emphasizing symmetry principles throughout . After an introduction of the basic postulates and techniques, the b ook discusses time-independent perturbation theory, angular momentum, identical particles, scattering theory, and time-dependent perturbatio n theory. It concludes with several lectures on relativistic quantum m echanics and on many-body theory.
