Rotationally invariant dynamical lattice regulators for Euclidean quantum field theories

Tsogtgerel Gantumur

We introduce a dynamical lattice regulator for Euclidean quantum field theories on a fixed hypercubic graph $\Lambda \simeq {\mathbb{Z}}^d$, in which the embedding $x:\Lambda \to {\mathbb{R}}^d$ is pr…
