On the modified Palm version

Abstract: The Palm version of a stationary random measure is an important tool in probability. It is however not well known that there are in fact two Palm versions, with related but different interpretations. For lack of better terms, call the well known version standard and the less known version modified. In this talk we shall focus on the modified Palm version and its interpretation using coin tosses as a transparent example. The concepts of shift-coupling and mass-stationarity will play a key role.

Existence and absence of percolation for outdegree-one random graphs

Abstract: In this talk, we will discuss the existence of Poisson out degree one random graphs obtained like a stopped germs/grains dynamic. We will focus on a stopped line segment dynamic and a stopped Brownian dynamic. We obtain the existence of these two models consequently of a general result of percolation which generalize the Peter Hall famous theorem about subcritical phase in the Poisson boolean model. The second part of the talk concerns the absence of percolation results about some out degree one models built thanks to the existence result. A growing segment dynamic does not percolate if the law which distributes the velocities has a 3-th moment.

This is a joint work with David Dereudre and David Coupier.

Hyperuniformity - A Geometric State of Matter

Abstract: Hyperuniformity describes an anomalous suppression of large-scale density fluctuations. It can be found in systems that are isotropic and locally amorphous like a liquid but at the same time macroscopically uniform like a crystal.

This rigorous mathematical characterization of unique geometric and stochastic properties allows for an exploration of new states of matter, which are endowed with unique physical properties.
