Supersymmetry: Basics and Concepts provides an overall survey of supersymmetry from a unified and up-to-date viewpoint. The author's approach reflects the free logic that characterizes present day research rather than fact-bound induction. Main topics include: simple systems with supersymmetry taken from particle mechanics, the classical limit of supersymmetric quantum mechanics, the double cover of the Lorentz group and other group theoretical matters, and a representative sample process involving supersymmetric lepton-photon interactions.
