Abstract
As a counterpart to best approximation in normed linear spaces, the best coapproximation was introduced by Franchetti and Furi. In this paper, we shall consider the relation between coproximinality M in X and L p(S,M) in L p(S,X). Finally we give some results in cochebyshev subspaces and additional subspaces.
