Title: Pyramidal traveling fronts of a time periodic diffusion equation with degenerate monostable nonlinearity Authors: Zhen-Hui Bu (Northwest A\&F Univ., Yangling, Shaanxi, China) Chen-Lu Wang (Northwest A\&F Univ., Yangling, Shaanxi, China) Xin-Tian Zhang (Northwest A\&F Univ., Yangling, Shaanxi, China) 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. Submitted August 8, 2022.
