[Insalate Di Matematica]

Dear all,

As part of the series of seminars "Insalate di Matematica", *Elisa
Marini* (Università
degli Studi di Padova) will give a talk.
The speaker will deliver the talk *in presence* and the meeting will also
be broadcasted *online* (see below for more information).

Here the details:

*Date and time*: *19th of April 2023, 4:00 pm (CET)*

*Title*: "Noise-induced oscillations for the mean-field dissipative contact
process."

*Abstract*: In this talk, we will introduce a dissipative  version of the
contact process with mean-field interaction admitting a simple
epidemiological interpretation. In particular, 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 internal to the system, that
induces persistent oscillatory behaviors reminiscent of the emergence of
pandemic waves in real epidemics.

*Keywords*:  contact process, noise-induced oscillations, propagation of
chaos, diffusion approximation

*Information to attend in room 3014*
The seminar will take place in room 3014, at the building U5-Ratio,
Università degli Studi di Milano Bicocca.

*Information to attend online *
