| Abstract: | In this paper, three different kinds of best simultaneous Lp-approximations are introdaced and their various properties, are discussed. We obtain the sufficient and necessary conditions to the existence of the elements of best simultaneous Lp-approximation. In addition, the representatives of the best simultaneous Lp-approximation values are given. |
