Abstract

In this paper we prove some results related to the problem of isomorphically classifying the complemented subspaces of Xp. We characterize the complemented subspaces of Xp which are isomorphic to Xp by showing that such a space must contain a canonical complemented subspace isomorphic to Xp. We also give some characterizations of complemented subspaces of Xp isomorphic to p 2.
