Varadhan's decomposition of shift-invariant closed uniform forms for large scale interacting systems on general crystal lattices

We prove a uniform version of Varadhan decomposition for shift-invariant closed uniform forms associated to large scale interacting systems on general crystal lattices. In particular, this result includes the case of translation invariant processes on Euclidean lattices ${\mathbf{Z}}^d$ with finite range. Our result generalizes the result of arXiv:2009.04699 which was valid for systems on transferable graphs. In subsequent research, we will use the result of this article to prove Varadhan’s decomposition of closed $L^2$-forms for large scale interacting systems on general crystal lattices.
