Query: Large deviations for fast transport stochastic RDEs with applications to
  the exit problem   We study reaction diffusion equations with a deterministic reaction term as
well as two random reaction terms, one that acts on the interior of the domain,
and another that acts only on the boundary of the domain. We are interested in
the regime where the relative sizes of the diffusion and reaction terms are
different. Specifically, we consider the case where the diffusion rate is much
larger than the rate of reaction, and the deterministic rate of reaction is
much larger than either of the random rate of reactions.
