This is a collection of pedagogically written articles on quantum chromodynamics. Based on
lectures given over the past years to graduate students the articles are ideally suited as an
introduction into modern research. The book contains concepts and applications of lattice gauge
theories finite temperature field theory an article on the method of sum rules in QCD and so
on. Furthermore axial anomalies the Skyrme model and recent developments of supersymmetric QCD
are discussed in depth. A second volume on phenomenology is in preparation.
