A l1-predual which is not isometric to a quotient of C(alpha)
Dale E. Alspach
Abstract
About twenty years ago Johnson and Zippin showed that every separable L1(mu)-predual was isometric to a quotient of C(Delta ), where Delta is the Cantor set. In this note we will show that the natural analogue of the theorem for l1-preduals does not hold. We will show that there are many l1-preduals which are not isometric to a quotient of any C(K)-space with K a countable compact metric space. We also prove some general results about the relationship between l1-preduals and quotients of C(K)-spaces with K a countable compact metric space. The results in this paper were presented at the Workshop on Banach Space Theory in Merida, Venezuela, January 1992.
