Quasi-stationary distributions and population processes
Sylvie Méléard, Denis Villemonais
This survey concerns the study of quasi-stationary distributions with a specific focus on models derived from ecology and population dynamics. We are concerned with the long time b…
A rigorous model study of the adaptative dynamics of Mendelian diploids
Pierre Collet, Sylvie Méléard, J. A. J. Metz
Adaptive dynamics so far has been put on a rigorous footing only for clonal inheritance. We extend this to sexually reproducing diploids, although admittedly still under the restri…
Quantization based recursive Importance Sampling
Noufel Frikha, Abass Sagna
We investigate in this paper an alternative method to simulation based recursive importance sampling procedure to estimate the optimal change of measure for Monte Carlo simulations…
Perturbations of diagonal matrices by band random matrices
Florent Benaych-Georges, Nathanaël Enriquez
We exhibit an explicit formula for the spectral density of a (large) random matrix which is a diagonal matrix whose spectral density converges, perturbated by the addition of a sym…
Linking progressive and initial filtration expansions
Younes Kchia, Martin Larsson, Philip Protter
In this paper we study progressive filtration expansions with random times. We show how semimartingale decompositions in the expanded filtration can be obtained using a natural lin…
Random right eigenvalues of Gaussian quaternionic matrices
Florent Benaych-Georges, Francois Chapon
We consider a random matrix whose entries are independent Gaussian variables taking values in the field of quaternions with variance . Using logarithmic potential theory, we p…
