Proceedings of the International Workshop on Variational Calculations in Quantum Field Theory, Wangerooge, West Germany, 1-4 September 1987 /

The contributions in this conference proceedings present an alternative approach to solving the Quantum Field Theory problem using the variational approach. Many different issues are visited using this approach Yang Mills Theory, going beyond the Guassian Approximation, in QCD and QED.
