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 Z(X):=(z+Xz)zZd\displaystyle\mathbb{Z}(\mathbf{X}):=(z+X_z)_{z\in\mathbb{Z}^d} be the perturbed lattice that is the lattice Zd\mathbb{Z}^d perturbed by independent and identically random variables (Xz)zZd(X_z)_{z\in\mathbb{Z}^d} taking values in Rd\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 d3d\geq 3 in recent paper. In this paper, when random variables (Xz)zZd(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 d4d\geq 4. Also, as a consequence of the above, we show that when random variables (Xz)zZd(X_z)_{z\in\mathbb{Z}^d} follow the uniform distribution, phase transitions related to the tolerance can be seen in d4d\geq 4.
