Abstract
AbstractWe prove the Bernoulli property for determinantal point processes on $ \mathbb{R}^d $ with translation-invariant kernels. For the determinantal point processes on $ \mathbb{Z}^d $ with translation-invariant kernels, the Bernoulli property was proved by Lyons and Steif [Stationary determinantal processes: phase multiplicity, bernoullicity, and domination. Duke Math. J.120 (2003), 515–575] and Shirai and Takahashi [Random point fields associated with certain Fredholm determinants II: fermion shifts and their ergodic properties. Ann. Probab.31 (2003), 1533–1564]. We prove its continuum version. For this purpose, we also prove the Bernoulli property for the tree representations of the determinantal point processes.

For determinantal point processes on Zd with translation-invariant kernel and the counting measure, Lyons and Steif [5] and Shirai and Takahashi [12] independently proved the Bernoulli property, the latter giving a sufficient condition for the weak Bernoulli property under the assumption K : Zd × Zd → C satisfying (1), (2), Spec(K) ⊂ (0, 1), and (4)

Summary
Introduction and the main resultWe consider an isomorphism problem of measure-preserving dynamical systems among translation-invariant point processes on Rd such as the homogeneous Poisson point processes and the determinantal point processes with translation-invariant kernel functions.The homogeneous Poisson point process is a point process in which numbers of particles on disjoint subsets obey independently Poisson distributions. We call a Borel probability measure μ on Conf(X) a point process on X. Let μK be a determinantal point process on Rd with translation-invariant kernel K such that Under assumptions (1)–(3), there exists a unique (K, λ)-determinantal point process μ with the kernel function K [11, 13].
