DESCRIPTION:Speakers: Federico Gasparotto\n\nWe discuss how methods develo
ped in the context of perturbation theory can be applied to the computatio
n of lattice correlation functions\, in particular in the non perturbative
regime. The techniques we consider are integration-by-parts identities (s
upplemented with symmetry relations) and the method of differential equati
ons\, cast in the framework of twisted co-homology. We report on calculati
ons of correlation functions for a scalar $\\lambda \\phi^4$ theory and la
ttices of small size\, both in Euclidean and Minkowskian signature.\n\nhtt
