Majorant Topologies on Inner Product Spaces,uct is jointly continuous). Section 3 deals with orthonormal systems. Sections 5–7 discuss the existence and topological properties of fundamental decompositions in terms of majorants. In Section 8 the study of the projection problem is carried on. The following results should be specially mentioned

The Geometry of Krein Spaces, 1–2 deal with their global properties. In Sections 4, 7, 9, 10 maximal semi-definite subspaces of Krein spaces are investigated, while Sections 3, 5, 6, 6 are essentially concerned with ortho-complemented subspaces. Theorems 1.3, 3.4, 3.5, 4.2, 5.3, 5.7, 6.3, 7.1 and 9.1 give an idea of the content

Unitary and Selfadjoint Operators in Krein Spaces,n 3) as well as basic properties and the location of spectra of unitary and selfadjoint operators (Sections 4–7). In Section 8 it is proved that every continuous linear operator of a Hilbert space has a unitary dilation in a Krein space. Theorems 3.5, 3.10, 5.1, 5.5, 6.1, 7.5, 8.6 and Lemma 4.7 can
