Title: Convergence in comparable almost periodic reaction-diffusion systems with Dirichlet boundary conditions Authors: Feng Cao (Nanjing Univ. of Aeronautics, Jiangsu, China) Yelai Fu (Nanjing Univ. of Aeronautics, Jiangsu, China) Abstract: In this article, we study the asymptotic dynamics in nonmonotone comparable almost periodic reaction-diffusion systems with Dirichlet boundary condition, which are comparable with uniformly stable strongly order-preserving system. By appealing to the theory of skew-product semiflows, we obtain the asymptotic almost periodicity of uniformly stable solutions to the comparable reaction-diffusion system.
