IN A STUDY of the properties of bases in nuclear Frechet spaces, Dynin and Mitiagin [5] proved that in such spaces every Schauder basis is an absolute basis; another proof of this interesting result was given by Mitiagin [7]. Replacing the sequence space l1 in the definition of nuclear maps by the nuclear sequence space Λ(α) of power series the second author initiated, in [10], a study of Λ(α)- nuclear spaces and this study is presented in greater depth in a recent paper of the authors [3]. In this paper we introduce the notion of Λ(α)-basis in locally convex spaces.- The Problem of "Total Translativity" for Hausdorff Methods

The problem of the total translativity of Holder and Cesaro methods has been considered earlier by Kuttner [3]. In the present note we are concerned with the more general problem of the total translativity of Hausdorff methods and we prove that a Hausdorff method, satisfying suitable restrictions, is totally translative if, and only if, it is the Cesaro method or a trivial modification of that method.- Series-To-Series Quasi-Hausdorff Transformations
