In this paper we establish the existence and uniqueness of global solutions
(in time), as well as the existence, regularity and stability (upper
semicontinuity) of the attractor for the semigroup generated by the solutions
of a two-dimensional nonlinear hyperbolic-parabolic coupled system with
fractional Laplacian. In addition, we also obtain the existence of an
exponential attractor and show that this attractor has a finite fractal
dimension in a space containing the phase space of the dynamical system.
