Wave Front Formation in Singular Perturbation Problems

Over the past two decades, considerable progress has been made on wave front formation in singularly perturbed partial differential equations. Applications occur in many important areas in physical and biological sciences. Various methods, including numerical simulation, formal series expansions, maximum principle, energy methods, spectral methods, topological method and invariant manifold theory have been used. The speakers will discuss new physical models that generate sharp wave front solutions, and will describe new mathematical techniques for studying wave front formations. Our emphasis is on equations in higher dimensional spaces, or equations with higher order differential operators.
