"A characterization of best polynomial approximation in spaces
of continuous functions on compact sets (Kolmogorov's theorem)"

By

Zeliha Ural

Abstract: Given Banach
space X, we define best approximation from a finite dimentional
subspace X_n of  X. We discuss the existence and
uniqueness of best approximation. We mainly concern with Kolmogorov's
theorem for the best approximation in space C(A) of continuous real or complex
valued functions on the compact Hausdorff topological space A.

Tea and cookies will be served before the
seminar.
