Abstract: | Lattice field theories are described as a way to regularize continuum quantum field theories. They are obtained by replacing
ordinary space time by a lattice, space time derivatives by suitable differences and Minkowski by Euclidean space. The connection
between a quantum field theory isd space dimension and classical statistical mechanics in (d+1) dimensions is brought outvia elementary examples. The problem of regaining the continuum limit and of handling nonabelian gauge theories are briefly discussed. |
