Stability of invariant sets. (Russian) Zbl 0658.34045

The author proves a number of technical lemmas concerning stability and pseudostability of invariant sets, including a generalization of the criterion of T. Ura [Comm. Math. Univ. Sao Paulo 8, (1960)]. The article is difficult to read, since symbolism is not defined, and either one has to search other literature or to make an intelligent guess which symbol denotes an orbit, and which denotes a neighbourhood of a set, etc.
