    • Best simultaneous approximation in a normed linear space 

      Nairn, Dean C. (Rensselaer Polytechnic Institute, Troy, NY, 1976-12)
      The problem we consider is the approximation of m elements (xₗ,...,xₘ) in a normed linear space by one element in a subset of that normed linear space. To each element in the ordered m-tuple (xₗ,...,xₘ) we associate ...
