Extension of Isometries,The main result in this chapter is a theorem in [1] on the extension of isometries φ: V →V between ⊥-closed subspaces of a sesquilinear space E (Theorems 5 and 9 below).

Quadratic Forms,Quadratic forms are closely related to orthosymmetric sesquilinear forms and, to a large extent, they behave very similarly. In fact, the two concepts partly overlap (cf. Example 2 in Section 3 below).

,Diagonalization of ℵ0-Forms,ecomposition into mutually orthogonal lines is impossible. The problem of “normalizing” bases brings us to stability and the beginner is confronted with the first Ping-Pong style proof with its characteristic back-and-forth argument (Theorem 2). These matters are basic and their knowledge is tacitly assumed in the rest of the book.
