Abstract:
A complete characterization of the extremal
subsets of Hilbert spaces,
which is an infinite-dimensional generalization
of the classical Jung theorem, is given.
The behavior of the set of points near
the Chebyshev sphere of such a subset with respect to
the Kuratowski and Hausdorff measures of noncompactness
is investigated.
Keywords:
Jung theorem, Jung constant, extremal subset of a Hilbert space, Chebyshev sphere, Kuratowski and Hausdorff noncompactness measures.
