Boundedly compact
WebJun 1, 2003 · Since the sequence {P k} above is bounded and lies in span 1 H d (with respect to L p ([0,1] d)), it also illustrates that span 1 H d, and hence span n H d, are not boundedly compact. Another example of an approximatively compact set that is not boundedly compact is any closed infinite-dimensional subspace of a uniformly convex … WebMar 26, 2024 · If a) $ M $ is a boundedly-compact set or b) $ X $ is uniformly convex and $ M $ is locally compact, then $ M $ is a sun (under the extra hypothesis "X is smooth" , $ M $ is a convex set). A Chebyshev set with a continuous metric projection in a smooth reflexive space is convex, and in $ C [ 0 , 1 ] $ it is a sun. ...

WebNov 25, 2024 · When one adds the hypothesis that the limit distance is boundedly compact, the uniform convergence on compact sets can be obtained, as stated in item (iv). Without the hypothesis on the boundedly compactness of the limit distance, the convergence result might be false, see the example in Remark 3.24.

WebAug 1, 2024 · We say that a subset E of F ( X, Y) is pointwise bounded provided for every x ∈ X, E [ x] is bounded in ( Y, d). We say that a metric space ( Y, d) is boundedly compact [5] if every closed bounded subset is compact. Therefore, if ( Y, d) is boundedly compact, then ( Y, d) is a locally compact, separable metric space and d is complete.
