چکیده انگلیسی
We characterize Ascoli spaces by showing that a Tychonoff space X is Ascoli iff the canonical map from the free locally convex space L(X) over X into Ck(Ck(X)) is an embedding of locally convex spaces. We prove that an uncountable direct sum of non-trivial locally convex spaces is not Ascoli. If a c0-barrelled space E is weakly Ascoli, then E is linearly isomorphic to a dense subspace of RÎ for some set Î. Consequently, a Fréchet space E is weakly Ascoli iff E=RN for some Nâ¤Ï. If X is a μ-space and a kR-space (for example, metrizable), then Ck(X) is weakly Ascoli iff X is discrete. If X is a μ-space, then the space Mc(X) of all regular Borel measures on X with compact support is Ascoli in the weakâ topology iff X is finite. The weakâ dual space of a metrizable barrelled space E is Ascoli iff E is finite-dimensional.
