Abstract: A subset of a metric space is -embedded in if every uniformly continuous function extends to a uniformly continuous function . Thus -embedding is the uniform analogue of -embedding. The Tietze extension theorem tells us exactly which subsets of metric spaces are -embedded. The uniform analogue would tell us exactly which subsets of metric spaces are -embedded. In this paper, a characterization of -embedded subsets of the Euclidean plane (or any normed linear space) is given.
