Geometrical notions and methods play an important role in both classical and quantum field theory, and a connection is a deep structure which apparently underli

Contemporary quantum field theory is mainly developed as quantization of classical fields. Therefore, classical field theory and its BRST extension is the neces

This book presents a basic introduction to quantum mechanics. Depending on the choice of topics, it can be used for a one-semester or two-semester course. An at
