Abstract.
We analyze the condition for instability and pattern formation
induced by additive noise in spatially extended systems. The
approach is based on consideration of higher moments which
extract out nonlinearities of appropriate order. Our analysis
reveals that cubic nonlinearity plays a crucial role for the
additive noise to a leading order that determines the
instability threshold which is corroborated by numerical
simulation in two specific reaction-diffusion systems.
