Some Superprojective Properties of Banach Spaces and Their Localizations

Abstract:

      In this article the relations between superprojective properties and local superpro- jective propcrtics of Banach space are discussed. For a reflexivc Banach space X, it is proved that X is l_p-subprojective space if and only if X^* is l_p-superprojective space, X is local l_p-sub- projective spacc if and only if X^* is local l_p-superprojective space and X is local subprojective space if and only if X^* is local superprojective space, where 1/p+1/q=1.
