Abstract

This note presents a construction of generalized random fields (prop. 1 and 2). In particular if we base our construction on a given Euclidean invariant field, the new one will have the same invariance. Similarly the properties of T-positivity and clustering carry over to the new models. A Gaussian input will give rise to non-Gaussian fields such as e.g. the “ultralocal” ones.
