Pyramidal traveling fronts of a time periodic diffusion equation with degenerate monostable nonlinearity

Abstract

This article focuses on the nonplanar traveling fronts of degenerate monostable time periodic reaction-diffusion equations in Rn with n≥3. By constructing a couple of proper supersolution and subsolution, we prove the existence of periodic pyramidal traveling front in R3 and then in Rn with n>3.
