The operators \pi_G of best approximations and continuous metric projections

다국어 초록 (Multilingual Abstract)

In this paper, we shall consider some properties of the metric projection as a set valued mapping. For a set G in a metric space E, the mapping \pi_G ; x \rightarrow \pi_G(x) of E into 2^G is called set valued metric projection of E onto G. We investigated the properties related to the projection P_{S(\cdot)}(\cdot) and \pi_{S(\cdot)}(\cdot) as one-sided best simultaneous approximations.
