Global Existence and Convergence Rates for the Strong Solutions in H2 to the 3D Chemotaxis Model

We are concerned with a 3D chemotaxis model arising from biology, which is a coupled hyperbolic-parabolic system. We prove the global existence of a strong solution when H2-norm of the initial perturbation around a constant state is sufficiently small. Moreover, if additionally, L1-norm of the initi...
