Uniqueness and differential characterization of approximations from manifolds of functions
Uniqueness and differential characterization of approximations from manifolds of functions
Our purpose is to present the following result (definitions will be found below).THEOREM.Let M be a connected n-dimensional Haar embedded manifold in C(K) whose restrictions, to any set ofn + l points [ki} CK, form a closed hypersurface of C({ki}).Then M is a Chebyshev set.
