In this paper r stands for the set of real numbers, K will denote the field of real or complex numbers (we will call them scalars), X a Hausdorff normal topological space and E a quasi-complete locally convex space space over K with topology generated by an increasing family of semi-norms [[parallel]*[parallel].

In particular, when Y is a (real) separated locally convex space, the choice H = cl(K) is allowed in (c02); and Theorem 4.

If a locally convex space X admits an operator without closed invariant subspaces then L(X) is strongly generated by two elements.
More exactly, if in an F-space the Hahn-Banach theorem holds, then that space is necessarily locally convex space (see e.
We then intend to use the theory of mixed topologies to give some general properties of the locally convex space (M(X), [beta](X)).
We say that a locally convex space (E, [tau]) is Mackey complete (M-complete) if its bounded structure Bt admits a fundamental system B of Banach discs ("completent" discs) that is, for every B in B, the vector space generated by B is a Banach space when endowed with the gauge [parallel]*[[parallel].
This paper deals with the two following general problems: (i) for any locally convex space E, characterize in terms of E the existence of a non-empty set [SIGMA] in [N.
