Bases and Structure of the Space,es of . like weak sequential completeness, separability, reflexivity, weak conditional compactness and the dimension (finite or infinite). In the first section some results are established on the first two properties of . or of .*. The following paragraph has to do with reflexivity. In both sections

Bases for Hilbert Spaces,fact that in every separable Hilbert space . there exists a total orthonormal sequence, hence an orthonormal basis for . It follows that a basis for . is orthonormal if and only if it is normal and that such a basis is unconditional.

Decompositions,of a sequence of elements of . and, in the same time, to define . to be an .-space. Such a basis of subspaces is called a decomposition and, if the subspaces are closed, a Schauder decomposition. The closure of the subspaces is intimately connected with the continuity of projections onto these subsp

Some Results on Generalized Bases for Linear Topological Spaces,ds of almost all requirements used for the definition of a basis. Beginning with the absolute minimum one takes a linear topological space X, does not use the concepts of totalness and countability and avoids all mention of series expansions. Thus, the starting point will be a family {x.} of element
