Abstract

[Abstract]: The computer algebra routines documented here empower you to reproduce and check many of the details
described by Roberts (2006). We consider a small spatial
domain, representing a finite element, and apply stochastic centre
manifold techniques to derive a one degree of freedom model for the
dynamics in the element. The approach automatically parametrises the
microscale structures induced by spatially varying stochastic noise
within the element. The crucial aspect of this work is that we explore
how many noise processes may interact in nonlinear dynamics.
