Abstract

LetX be a convex compact in a real Banach spaceE. An actionU(t) (t≥0) of the semigroup + onX is called dissipative if allU(t) are nonexpanding: ∥U(t)x 1U(t)x 2∥≤∥x 1x 2∥. Let the spaceE be strongly normed. We prove that all trajectoriestU(t)x of the dissipative flowU(t) are converging fort→∞ if there are no two-dimensional Euclidean subspaces in the spaceE. In every two dimensional non-Euclidean spaceE (not necessarily strongly normed) all trajectories of the flow under consideration are converging.
