DESCRIPTION:Speakers: Elisa Marini (Paris-Dauphine)\n\nIn this talk\, we w
 ill introduce a dissipative version of the contact process with mean-field
  interaction admitting a simple epidemiological interpretation. In particu
 lar\, we will focus on the thermodynamic limit of the process\, providing 
 a law of large numbers (propagation of chaos) and a central limit theorem 
 for the corresponding normal fluctuations. These results reveal that it is
  the noise\, which is only present in the finite-size system and is intern
 al to the system\, that induces persistent oscillatory behaviors reminisce
 nt of the emergence of pandemic waves in real epidemics. \nThe talk is ba
 sed on a joint work with Paolo Dai Pra (University of Verona). \n\nhttps:
