摘要：

We consider a hyperbolic-parabolic system derived from a limiting case of chemotaxis model in an exterior domain. By energy method we prove global existence for the initial-boundary value problem in an exterior domain when the initial data is a small perturbation around constant equilibrium s-tates, and the solutions converge to the states at an algebraic decay rate as time goes to infinity.
