Title: Entropy production in nondegenerate diffusions: large times and small noises
Abstract: Entropy production (EP) is a key quantity from thermodynamics which quantifies the irreversibility of the time evolution of physical systems. I will start the presentation with a general introduction to the different approaches to defining EP. Then, I will focus on the context of nondegenerate diffusions and I will describe the large-deviation properties of EP as time goes to infinity. I will also explain how the behaviour of the corresponding rate function boils down to the study of the smallest eigenvalue for a family of differential operators with a small parameter.
