Abstract:

This paper sets out a theoretical framework for approximating the attractor $\mathcal {A}$ of a semigroup $S(t)$ defined on a Banach space X by a q-step semidiscretization in time with constant steplength k. Using the one-step theory of Hale, Lin and Raugel, sufficient conditions are established for the existence of a family of attractors $\{ {\mathcal {A}_k}\} \subset {X^q}$, for the discrete semigroups $S_k^n$ defined by the numerical method. The convergence properties of this family are also considered. Full details of the theory are exemplified in the context of strictly $A(\alpha )$-stable linear multistep approximations of an abstract dissipative sectorial evolution equation.
