Short Talk: Imanol Nuñez

In this talk, I will discuss a particular system of partially exchangeable Markov chains. I will begin with a motivating example, the averaging process, which we will reinterpret within a framework involving a countable collection of Markov chains. After reviewing the definition of exchangeability and key known results, I will present a characterization of partially exchangeable Markov chains whose finite subcollections remain Markovian. Finally, I will explore concrete examples and highlight their connection to the averaging process. This talk is based on current work with Adrián González Casanova, Noemi Kurt and José-Luis Pérez.
