Recherches actuelles

  • Systèmes dynamiques basse dimension (propriétés statistiques, complexité, chaos).
  • Systèmes dynamiques étendus (dimension, entropie).
  • Processus stochastiques (mesures quasi invariantes, théorèmes limites de rapport, aspects statistiques).
  • Mécanique statistique (propriétés de concentration, fluctuations).
  • Mécanique des milieux continus (barres de Hopkinson, analyse des signaux, propriétés des matériaux).
