• Sommario/riassunto: Quantum chromodynamics is the fundamental theory of strong interactions. It is a physical theory describing Nature. <i>Lectures on Quantum Chromodynamics</i> concentrates, however, not on the phenomenological aspect of QCD; books with comprehensive coverage of phenomenological issues have been written. What the reader will find in this book is a profound discussion on the theoretical foundations of QCD with emphasis on the nonperturbative formulation of the theory: What is gauge symmetry on the classical and on the quantum level? What is the path integral in field theory? How to define the pa
