Abstract:
      In this note, the author discusses the problem of best simultaneous approximation by function pairs. The existence and characterization theorems of the best simultaneous approximation in L1 and L norms are obtained respectively, and some rezults of [ 1 ] are the special case of the theorems of the paper.
