Rigidity and non-rigidity for uniform perturbed lattice (1909.01555v1)

Published 4 Sep 2019 in math.PR, math-ph, and math.MP

Abstract: A point process on the topological space S is at most countable subset without a random accumulation point in S. In studies of the point processes, there is a problem of seeing the properties of rigidity and tolerance, and this problem is studied actively in recent years. When let $\displaystyle\mathbb{Z}(\mathbf{X}):=(z+X_z){z\in\mathbb{Z}d}$ be the perturbed lattice that is the lattice $\mathbb{Z}d$ perturbed by independent and identically random variables $(X_z){z\in\mathbb{Z}d}$ taking values in $\mathbb{R}d$, regarding the Gaussian perturbed lattice, Peres and Sly showed that there exist the phase transitions with respect to the rigidity and the tolerance when $d\geq 3$ in paper. In this paper, when random variables $(X_z){z\in\mathbb{Z}d}$ follow uniform distribution, we show the mutually absolute continuity of the measure without one point and the original measure on a restricted set of spaces of the point process in $d\geq 4$. Also, as a consequence of the above, we show that when random variables $(X_z){z\in\mathbb{Z}d}$ follow the uniform distribution, phase transitions related to the tolerance can be seen in $d\geq 4$.
