This thesis falls within the field of limit theorems for Markov chains. We consider sequences of Markov chains, and focus on proving double asymptotics for such processes as both the time and the index in the sequence tend to infinity. In a first phase we will focus on the prisonners model in which a finite number of random walkers are constrained to stay close to each other. Our goal is to determine the limit behavior as the time and the number of prisonners is increasing, using the Hodge decomposition of an additive functionnal of a random walk on a finite graph, in line with previous work of Boissard, Cohen, Espinasse and Norris. Then we develop a generalisation of this model in which the Hodge decomposition can be used to prove limit th...
