Abstract

Let K be a nonempty subset of a Hausdorff topological vector space X, and let f be a real‐valued continuous function on X. If for each x = (x1, x2, …, xn) ∈ Xn, there exists k0 ∈ K such that FK(x)=∑i=1nfxi-k0=inf ∑i=1nf(xi-k):k∈K, then K is called f‐simultaneously proximal and k0 is called f‐best simultaneous approximation for x in K. In this paper, we study the problem of f‐simultaneous approximation for a vector subspace K in X. Some other results regarding f‐simultaneous approximation in quotient space are presented.
