The Levy-Steinitz rearrangement theorem for duals of metrizable spaces

Abstract

Extending the classical Levy-Steinitz rearrangement theorem, which in turn extended Riemann's theorem, Banaszczyk proved in 1990/93 that a metrizable, locally convex space is nuclear if and only if the domain of sums of every convergent series (i.e. the set of all elements in the space which are sums of a convergent rearrangement of the series) is a translate of a closed subspace of a special form. In this paper we present an apparently complete analysis of the domains of convergent series in duals of metrizable spaces or, more generally, in (DF)-spaces in the sense of Grothendieck.
