Fluctuations near homogeneous states of chemical reactions with diffusion

Conditions are given under which a space-time jump Markov process describing the stochastic model of non-linear chemical reactions with diffusion converges to the homogeneous state solution of the corresponding reaction-diffusion equation. The deviation is measured by a central limit theorem. This limit is a distribution-valued Ornstein.Uhlenbeck process and can be represented as the mild solution of a certain stochastic partial differential equation.
