summary | In the fluid limit set-up, pure jump Markov processes follow a central limit theorem that leads to the so-called diffusion or Langevin approximation. Here we compare the large deviations between the jump process and its approximation for the problem of escape from a domain. In dimension one, we exhibit an example with a domain a, b where the jump process asymptotically escapes from a and its approximation from b. |
