Process-level large deviations for nonlinear Hawkes point processes

Lingjiong Zhu (2014)

Annales de l'I.H.P. Probabilités et statistiques

In this paper, we prove a process-level, also known as level-3 large deviation principle for a very general class of simple point processes, i.e. nonlinear Hawkes process, with a rate function given by the process-level entropy, which has an explicit formula.

Processus de Markov et désintégrations régulières

Laurent Schwartz (1977)

Annales de l'institut Fourier

Un théorème classique exprime qu’à partir d’un semi-groupe ( P t ) t 0 d’opérateurs sur l’espace des fonctions continues tendant vers 0 à l’infini, P s + t = P t , P s 0 , P t l = 1 , t P t f continue, P 0 = I , on peut construire un processus markovien “standard”, à trajectoires réglées et continues à droite, quasi-continu à gauche ; l’espace des états E est supposé localement compact à base dénombrable d’ouverts. Nous supposons ici que l’espace des états est seulement universellement mesurable dans un souslinien complètement régulier ; le processus...

Product d -actions on a Lebesgue space and their applications

I. Filipowicz (1997)

Studia Mathematica

We define a class of d -actions, d ≥ 2, called product d -actions. For every such action we find a connection between its spectrum and the spectra of automorphisms generating this action. We prove that for any subset A of the positive integers such that 1 ∈ A there exists a weakly mixing d -action, d≥2, having A as the set of essential values of its multiplicity function. We also apply this class to construct an ergodic d -action with Lebesgue component of multiplicity 2 d k , where k is an arbitrary positive...
