Abstract
We study the effect of the boundary conditions on the spontaneous nucl eation and evaporation of excited domains in the bistable regime of an activator-inhibitor stochastic system. In such a regime a quasivariat ional approximation can be used to obtain the stationary distribution. The nucleation and evaporation rates of the resulting nonuniform stru ctures are investigated using a piecewise-linear dynamics to obtain an alytical results.
