Direct proof of unconditional asymptotic consensus in the Hegselmann–Krause model with transmission‐type delay

open access: yesBulletin of the London Mathematical Society, Volume 53, Issue 5, Page 1312-1323, October 2021., 2021
Abstract We present a direct proof of asymptotic consensus in the non‐linear Hegselmann–Krause model with transmission‐type delay, where the communication weights depend on the particle distance in phase space. Our approach is based on an explicit estimate of the shrinkage of the group diameter on finite time intervals and avoids the usage of Lyapunov ...

HALF-SPACE MACDONALD PROCESSES

open access: yesForum of Mathematics, Pi, 2020
Macdonald processes are measures on sequences of integer partitions built using the Cauchy summation identity for Macdonald symmetric functions. These measures are a useful tool to uncover the integrability of many probabilistic systems, including the ...

Boundedness of one‐dimensional branching Markov processes

open access: yesInternational Journal of Stochastic Analysis, Volume 10, Issue 4, Page 307-332, 1997., 1997
A general model of a branching Markov process on ℝ is considered. Sufficient and necessary conditions are given for the random variable to be finite. Here Ξk(t) is the position of the kth particle, and N(t) is the size of the population at time t. For some classes of processes (smooth branching diffusions with Feller‐type boundary points), this results

Thermodynamic Limit for Spin Glasses. Beyond the Annealed Bound [PDF]

open access: yes, 2008
Using a correlation inequality of Contucci and Lebowitz for spin glasses, we demonstrate existence of the thermodynamic limit for short-ranged spin glasses, under weaker hypotheses than previously available, namely without the assumption of the annealed ...

Balls left empty by a critical branching Wiener process

open access: yesInternational Journal of Stochastic Analysis, Volume 9, Issue 4, Page 531-549, 1996., 1996
At time t = 0 we have a Poisson random field on ℝd. Each particle executes a critical branching Wiener process starting from its position at time t = 0. Let RT be the radius of the largest ball around the origin of ℝd which does not contain any particle at time T. Our goal is to characterize the properties of the stochastic process {RT, T ≥ 0}.

ADDITIVITY PROPERTIES OF SOFIC ENTROPY AND MEASURES ON MODEL SPACES

open access: yesForum of Mathematics, Sigma, 2016
Sofic entropy is an invariant for probability-preserving actions of sofic groups. It was introduced a few years ago by Lewis Bowen, and shown to extend the classical Kolmogorov–Sinai entropy from the setting of amenable groups.

Spatial-temporal data mining procedure: LASR [PDF]

open access: yes, 2006
This paper is concerned with the statistical development of our spatial-temporal data mining procedure, LASR (pronounced ``laser''). LASR is the abbreviation for Longitudinal Analysis with Self-Registration of large-$p$-small-$n$ data.
