    Space-inhomogeneous branching Brownian motion in dimension 2

    19 décembre 2024 - 13:30None

    The study of the maximum displacement of branching particle systems have seen some remarkable progress in the past decade. In this talk, I will consider a variant of the branching Brownian motion in dimension 2 for which the branching rate depends on the direction of the particles. Together with David Geldbach and Michel Pain, we show that this type of space inhomogeneities can yield some extra polynomial lag terms compared to the homogeneous case.

    Matrix Distributions, Fractional Calculus and Insurance Risk Models

    25 février 2025 - 10:45Salle de séminaires IRMA

    In this talk some recent developments on matrix distributions and their connection to absorption times of inhomogeneous Markov processes will be discussed, in particular how and why such constructions are natural tools for modelling in applied probability, with a particular emphasis on non-life and life insurance applications. We also illustrate how certain extensions to the non-Markovian case involve fractional calculus and lead to matrix Mittag-Leffler distributions, which turn out to be a flexible and parsimonious class for the modelling of large but rare insurance loss events.
