March 24, J. Douglas Wright, Drexel University, Interaction manifolds in reaction diffusion systems

We consider a general planar reaction diffusion equation which we

hypothesize has a localized traveling wave solution.  Under

assumptions which are no stronger than those needed to prove the stability of a

single pulse, we prove that  the PDE has solutions which are roughly

the linear superposition of two pulses, so long as they move along

trajectories which are not parallel. In particular we prove that if

the initial data for the equation is close to the sum of two separated

pulses, then the solution converges exponentially fast to such a

superposition so long as the distance between the two pulses remains

sufficiently large.
