Best Interpolatory Approximation in Norm
✍ Frank Deutsch; Sizwe Mabizela 📂 Article 📅 1996 🏛 Elsevier Science 🌐 English ⚖ 542 KB

A theory of best approximation with interpolatory contraints from a finitedimensional subspace M of a normed linear space X is developed. In particular, to each x # X, best approximations are sought from a subset M(x) of M which depends on the element x being approximated. It is shown that this ``pa
