摘要
For a metric continuum X. we consider the hyperspaces C(X) and F-2(X) of all subcontinua and of all nonempty subsets of X with at most two points, respectively. In this paper we study classes of continua X for which F-2(X) can be embedded in C(X) and we also characterize locally connected continua X for which C(X) can be embedded in the Euclidean space R-4 and we prove a similar result for R-5.
