Csiszár indices and interpolating copulas

Cristina Butucea, Jean-François Delmas, Anne Dutfoy +1

We study various properties of -divergences and Csiszár indices between two probability distributions in very general setups for the convex function and for the probability…

Equivalence by coupling for heterogeneous SIS models*

Jean-François Delmas, Dylan Dronnier, Pierre-André Zitt

We consider the optimal allocation of (perfect) vaccine in an heterogeneous SIS model. Using a coupling approach, we explain how different models for the heterogeneity of the popul…

Topological Properties of the Effective Reproduction Number in an Heterogeneous SIS Model

Jean-François Delmas, Dylan Dronnier, Pierre-André Zitt

This present results lay the foundations for the study of the optimal allocation of vaccine in the simple epidemiological SIS model where one consider a very general heterogeneous…

Optimal Vaccination Strategies for an Heterogeneous SIS Model

Jean-François Delmas, Dylan Dronnier, Pierre-André Zitt

We study in a general mathematical framework the optimal allocation of vaccine in an heterogeneous population. We cast the problem of optimal vaccination as a bi-objective minimiza…

Infinite dimensional metapopulation SIS model with generalized incidence rate

Jean-François Delmas, Kacem Lefki, Pierre-André Zitt

We consider an infinite-dimension SIS model introduced by Delmas, Dronnier and Zitt, with a more general incidence rate, and study its equilibria. Unsurprisingly, there exists at l…

Transformations preserving the effective spectral radius of a matrix

Jean-François Delmas, Dylan Dronnier, Pierre-André Zitt

We discuss transformations on matrices that preserve the effective spectrum and/or the effective spectral radius.
