[Insalate Di Matematica]

Dear all,

We remind you *today*'s appointment of the series of seminars "Insalate di
Matematica".
Here are the details:

*Speaker*: *Federica Iacovissi* (Università degli Studi dell'Aquila)

*Date and time*: *14th of January 2025, 4:30 pm (CET)*

*Title*: "Large Deviations for Rational Models and the Matrix Product Ansatz
"

*Abstract*: A rational model is a stochastic model for the random
generation of words over a given alphabet A. This model defines a
probability measure μ_N on A^N in terms of matrices having rows and columns
labeled by a finite or countable set B. By enlarging the state space, we
show a natural approach to compute the large deviations rate functional for
the measure μ_N .
The invariant measures of several non equilibrium models of interacting
particle systems can be represented by the so-called Matrix Product Ansatz
which corresponds to a rational model with matrices labeled by B that is
countable infinite. We focus on the MPA representation of the
boundary-driven TASEP, and we discuss the approach for deriving a new LD
rate functional for the process.

*Keywords:* large deviations rate functional, Matrix Product Ansatz,
boundary-driven TASEP

*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.
