摘要: In these notes I wish to summarize some recent developments in relativistic quantum field theory (RQFT) which have led the idea that class of RQFT Euclidean description, i.e. at imaginary time, should be viewed as classical statistical mechanics interacting random walks and surfaces. Put differently, construction many models is a problem stochastic geometry. We shall see describe fluctuations matter degrees freedom - quarks, leptons, Higgs particles while surfaces “field force”, gauge fields. More precisely, (chromo-electric) flux sheets theories confinement phase.
