On best simultaneous approximation in quotient spaces

  • Published:
Analysis in Theory and Applications

Abstract

We assume that X is a normed linear space, W and M are subspaces of X. We develop a theory of best simultaneous approximation in quotient spaces and introduce equivalent assertions between the subspaces W and W + M and the quotient space W/M.
