Abstract: We consider an integro-partial differential equation of hyperbolic type with a cubic nonlinearity, in which no dissipation mechanism is present, except for the convolution term accounting for the past memory of the variable. Setting the equation in the history space framework, we prove the existence of a regular global attractor.

Keywords:  Hyperbolic equations with memory, dynamical systems, Lyapunov functionals, gradient systems, global attractors
