SOME RESULTS ABOUT BEST COAPPROXIMATION IN L^P（S,X）

As a counterpart to best approximation in normed linear spaces, the best coapproximation was introduced by Francbetti and Furl. 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...
