Translationally Invariant

Some articles on translationally invariant:

Path Integral Formulation - Quantum Field Theory - Schwinger-Dyson Equations
... If the functional measure turns out to be translationally invariant (we'll assume this for the rest of this article, although this does not hold for, let's say nonlinear sigma models) and if we ... the "master" Schwinger-Dyson equation or If the functional measure is not translationally invariant, it might be possible to express it as the product where M is a functional and is a translationally invariant measure ...
