Linear Transformations,ded for the development of the theory of bases. We begin by defining various abstract spaces, and we list their most important properties. Then we investigate linear transformations of one space into another, continue with some facts on conjugate spaces, and conclude with results for several spacial spaces.

Convergence of Series in Banach Spaces, Dvoretzky-Rogers theorem. The latter states the existence in every infinite dimensional Banach space of an unconditional series which is not absolutely convergent, a fact, which has been conjectured for about twenty years and which has been settled down by . and . in 1950.

Bases for Banach Spaces,aphs are devoted to retro-, shrinking, boundedly complete, unconditional, absolutely convergent and uniform bases. Some applications of summability methods on the theory of bases are given in the sixth section and in the last paragraph bases for the special spaces c., l.(l ≤ p < ∞), ., .. (l ≤ p < ∞), L. and .. are considered.
