Abstract: Using method of energy estimates and Gagliardo-Nirenberg type inequalities, the uniform boundedness and global existence of nonnegative solutions for a four-species predator-prey cross-diffusion model are proved when the space dimension is one.

Key words: predator-prey model, self-diffusion, cross-diffusion, uniform boundedness, global solution
