Discrete approximations of determinantal point processes on continuous spaces: tree representations and tail triviality

H Osada, S Osada - Journal of Statistical Physics, 2018 - Springer
We prove tail triviality of determinantal point processes μ μ on continuous spaces. Tail
triviality has been proved for such processes only on discrete spaces, and hence we have …

Number rigidity in superhomogeneous random point fields

S Ghosh, J Lebowitz - Journal of Statistical Physics, 2017 - Springer
We give sufficient conditions for the number rigidity of a large class of point processes in
dimension d= 1 d= 1 and 2, based on the decay of correlations. Number rigidity implies that …

H Osada, H Tanemura - … and Partial Differential Equations: Analysis and …, 2024 - Springer
Abstract The Airy\(_ {\beta}\) random point fields (\(\beta= 1, 2, 4\)) are random point fields
emerging as the soft-edge scaling limits of eigenvalues of Gaussian random matrices. We …

[HTML][HTML] Strong Markov property of determinantal processes with extended kernels

H Osada, H Tanemura - Stochastic Processes and their Applications, 2016 - Elsevier
Abstract Noncolliding Brownian motion (Dyson's Brownian motion model with parameter β=
2) and noncolliding Bessel processes are determinantal processes; that is, their space–time …

Palm measures and rigidity phenomena in point processes

S Ghosh - 2016 - projecteuclid.org
We study the mutual regularity properties of Palm measures of point processes, and
establish that a key determining factor for these properties is the rigidity-tolerance behaviour …

Cores of Dirichlet forms related to random matrix theory

H Osada, H Tanemura - 2014 - projecteuclid.org
We prove the sets of polynomials on configuration spaces are cores of Dirichlet forms
describing interacting Brownian motion in infinite dimensions. Typical examples of these …

A strong duality principle for equivalence couplings and total variation

AQ Jaffe - Electronic Journal of Probability, 2023 - projecteuclid.org
We introduce and study a notion of duality for two classes of optimization problems
commonly occurring in probability theory. That is, on an abstract measurable space (Ω, F) …
