We prove Kolmogorov's type characterization of best approximation for given \(L \in \mathscr{L}(W, V)\) in finite dimensional subspace \(\mathscr{V} \subset \mathscr{L}(W, V)\). This extends the results obtained by Malbrock for the case \(W=V=c_{0}\) and \(W=C(T), V=C(S)\). co 1995 Academic Press, I
