- ItemAttractors for semilinear equations of viscoelasticity with very low disspation(Berlin : Weierstraß-Institut für Angewandte Analysis und Stochastik, 2006) Gatti, Stefania; Miranville, Alain; Pata, Vittorino; Zelik, SergeyWe analyze a differential system arising in the theory of isothermal viscoelasticity. This system is equivalent to an integrodifferential equation of hyperbolic type with a cubic nonlinearity, where the dissipation mechanism is contained only in the convolution integral, accounting for the past history of the displacement. In particular, we consider here a convolution kernel which entails an extremely weak dissipation. In spite of that, we show that the related dynamical system possesses a global attractor of optimal regularity.
