Abstract

I give a brief introduction to particle interactions based on representations of Poincare Lie algebra. This is later generalized to interactions based on representations of the supersymmetry Lie algebra. Globally supersymmetric models with internal symmetry and locally supersymmetric models leading to supergravity theories are presented. I also discuss higher dimensional supergravity theories and some of their applications.
