Methods of Quantization

The present set of lecture notes gives both a status report and a survey of recent advances for the most important quantization methods in the field theories for elementary particle physics. The first part of the book introduces light-cone quantization as an interesting alternative to the commonly used covariant perturbation theory and functional-integral methods. Next, a general formalism for quantizing systems with constraints, the projection-operator approach, is presented and structural aspects of the renormalization problem for gauge invariant field theories are discussed. Finally, the mathematics underlying the functional-integral quantizaion is reviewed.Suitable as a reference for researchers in the field, the book will prove particularly useful for lecturers and gradjuate students in search of additional reading beyond the standard texts on quantum field theory.
