Large Deviation Results for Dynamics of Many Agent
Abstract: Large Deviation Theory quantifies how the probabilities of rare events decrease in the limit of small noise. We will start with giving an intuition of the theory for the empirical average of N independent and identically distributed random variables and compare Large Deviation results in the limit of large N with the Law of Large Numbers and the Central Limit Theorem. We then discuss the results for certain scaled Markov jump processes, which can also be used as models for agent dynamics or chemical species. Here, the scaling parameter is given by the number of agents or particles, N. As is well known, when N becomes large, the dynamics converge to the solution of an ordinary differential equation (ODE). But Large Deviation Theory allows us to also quantify the probabilities for realizations deviating from that limiting ODE path.
