I will start 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. Finally, I will discuss the behaviour of the corresponding rate function as the intensity of the noise goes to zero. ************************ Giacomo Di Gesù Dipartimento di Matematica Università di Pisa Largo Bruno Pontecorvo 5 56127 - Pisa, Italy giacomo.digesu@unipi.it<mailto:giacomo.digesu@unipi.it> https://sites.google.com/site/giacomodigesu/
