SOME RESULTS ABOUT BEST COAPPROXIMATION IN L^P(S, X)
《Analysis in Theory and Applications》2010年第1期69-75,共7页M. R. Haddadi N. Hejazjpoor H. Mazaheri 
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...
