Title: Existence of global solutions for a predator-prey model with cross-diffusion Author: Shenghu Xu (Northwest Normal Univ., Lanzhou, China) Abstract: In this article, we prove the existence of global classical solutions for a prey-predator model when the space dimension n<10. Under certain conditions on the coefficients of the reaction functions, the convergence of solutions is established for the system with large diffusion by constructing a Lyapunov function.
