On Spatial Point Processes with Uniform Births and Deaths by Random Connection
Résumé
This paper is focused on a class of spatial birth and death process of the Euclidean space where the birth rate is constant and the death rate of a given point is the shot noise created at its location by the other points of the current configuration for some response function f. An equivalent view point is that each pair of points of the configuration establishes a random connection at an exponential time determined by f, which results in the death of one of the two points. We concentrate on space-motion invariant processes of this type. Under some natural conditions on f, we construct the unique time-stationary regime of this class of point processes by a coupling argument. We then use the birth and death structure to establish a hierarchy of balance integral relations between the factorial moment measures. Finally, we show that the time-stationary point process exhibits a certain kind of repulsion between its points that we call f-repulsion.
