Research Abstract

Spatially localized traveling patterns appear ubiquitously in nature such as neural system, gas-discharge phenomena, chemical reaction, binary convection, and motion of true slime mold. They display a variety of dynamic patterns like annihilation, coalescence,and splitting via collisions or interaction with environments. For the comprehensive understanding of these phenomena, we combine several theoretical and numerical approaches like local bifurcation analysis of higher codimension, numerical path-tracking, and reduction to finite dimensional systems, which allow us to clarify the mathematical mechanism controlling behind those dynamics.
