About this title

Synopsis

The meeting encompassed all Euclidean quantum field theory descriptions that make direct reference to concepts from probability theory and statistical mechanics. Contributors examine the space-time discretized lattice field theories, and present optimized techniques that combine features of ordinary Monte Carlo methods, langevin equations, the microcanonical ensemble, overrelaxation, and cluster updatings. The subject of gravity is treated both from the point of view of stochastic quantization and the approach of discretizing space-time in an attempt to obtain a scheme that can be treated by numerical methods.
