Propagation d’épidémie sur des graphes connectés
Je présenterai un travail récent réalisé avec Grégory Faye concernant la propagation d’épidémies sur des graphes métriques. Après avoir rappelé quelques résultats sur le modèle SIR standard, j’expliquerai les motivations de notre modèle. Je présenterai les résultats théoriques en insistant sur les résultats asymptotiques. Je montrerai comment construire un schéma numérique adapté et fournirait plusieurs illustrations numériques.
