Best simultaneous \(L_{p}\) approximations. (English) Zbl 0957.41011

The paper deals with simultaneously approximation of \(n\) real-valued functions in \(L_p\). Some previous results concerning the problem in \(L_1\) and \(L_2\) norms and/or in \(L_p\) for a pair of functions \((n=2)\) are generalized.
