Stochastic Processes - Mathematics and Physics Proceedings of the 1st BiBoS-Symposium held in Bielefeld, West Germany, September 10-15, 1984

This second BiBoS volume surveys recent developments in the theory of stochastic processes. Particular attention is given to the interaction between mathematics and physics.
Main topics include: statistical mechanics, stochastic mechanics, differential geometry, stochastic proesses, quantummechanics, quantum field theory, probability measures, central limit theorems, stochastic differential equations, Dirichlet forms.
