LF-space In mathematics, an ''LF''-space is a topological vector space ''V'' that is a locally convex inductive limit of a countable inductive system of Fréchet spaces. This means that ''V'' is a direct limit of the system in the category of locally convex topological vector spaces and each is a Fréchet space. Some authors restrict the term ''LF''-space to mean that ''V'' is a strict locally convex inductive limit, which means that the topology induced on by is identical to the original topology on . The topology on ''V'' can be described by specifying that an absolutely convex subset ''U'' is a neighborhood of 0 if and only if is an absolutely convex neighborhood of 0 in for every n. ==Properties== An ''LF''-space is barrelled and bornological (and thus ultrabornological).
