               A cascade process of pulse (stripe) splitting can occur
               if the domain size increases for reaction-diffusion
               systems .  When we take a single pulse as the initial
               data on an initially small domain, the patterns we
               obtain finally depends on the domain growth speed.  For
               instance, the number of stripes increases as powers of
               2; namely, each stripe doubles as its size grows
               rapidly.  In order to describe the splitting process,
               we construct an invariant manifold near the onset of
               splitting, and derive the nonlinear ODE on it.
