Abstract: In this paper, we study of the dissipativity, global attractor and exponential attractor for a hyperbolic relaxation of the Caginalp phase-field system with singular nonlinear terms, with initial and homogenous Dirichlet boundary condition.

Keywords: Caginalp hyperbolic phase field, singular potential, Dirichlet boundary, bounded absorbing set, dissipativity, global attractor, exponential attractor
