Abstract
In nuclear and particle physics one is often faced with problems where perturbation theory is not applicable. An example of this is the description of bound states. Therefore, an exact solution of field theory to all orders is an unavoidable and interesting problem. Path integrals provide a framework for exact solutions in field theory. In this talk I will present an economical method of evaluating path integrals using the Feynman-Schwinger representation (FSR).
