Series in a Finite-Dimensional Space,arise rather nontrivial problems, which continue to be the subject of fruitful investigations. Analogies with the material studied in the present chapter will play an important role in the sequel, in the examination of features that are specific for the infinite-dimensional case.

Some Results from the General Theory of Banach Spaces,with nonlinear sum range, we need two theorems on the structure of infinite-dimensional spaces: Dvoretzky’s theorem on almost-Euclidean sections and Mazur’s theorem on basic sequences. Since these deep results are not incorporated in the standard functional analysis courses, their proof will be provided here in detail for the reader’s convenience.

Notations,In the book “Lemma 3.1.2” means “Lemma 2 in Section 1 of Chapter 3.” Theorems, definitions, and exercises are numbered in a similar fashion, each type with its independent numbers, i.e., in the text one can encounter both, say, Definition 2.1.1 and Theorem 2.1.1.

Background Material,In this short chapter we collected facts that are sufficiently well-known, the consideration of which may be regarded as an introduction to the main text.
