| Resumo: | [EN] We consider the large class (5 of locally convex spaces that includes, among others, the classes of (DF)-spaces and (LF)-spaces. For a space E in class (5 we have characterized that a subspace Y of (E , sigma (E , E ')) , endowed with the induced topology, is analytic if and only if Y has a sigma (E , E ')-compact resolution and is contained in a sigma(E , E ')-separable subset of E. This result is applied to reprove a known important result (due to Cascales and Orihuela) about weak metrizability of weakly compact sets in spaces of class (5. The mentioned characterization follows from the following analogous result: The space C(X) of continuous real -valued functions on a completely regular Hausdorff space X endowed with a topology xi stronger or equal than the pointwise topology tau p of C(X) is analytic iff (C(X) , xi) is separable and is covered by a compact resolution.functions on a completely regular Hausdorff space $X$ endowed with a topology $\xi $ stronger or equal than the pointwise topology $\tau _{p}$ of $C(X)$ is analytic iff $(C(X),\xi )$ is separable and is covered by a compact resolution. |
