Chain stability of closed sets, pp. 879-885.
ABSTRACT. This article deals with chain stability of closed sets. It is shown that chain stability is strictly stronger than absolute stability, but it may lack asymptotic stability. A characterization of chain stability is given in terms of neighborhoods.
