Examples A Frechet space (or, in short, an F-space) is a TVS with the following three properties: (a) it is metrizable (in particular, it is Hausdorff); (b) it is complete (hence a Baire space, in view of Proposition 8.3); (c) it is locally convex (hence it carries a metric d of the type considered in Proposition 8.1).

FormalPara Proof the art loft jax flWebRoughly speaking, a tame Fréchet space is one which is almost a Banach space. On tame spaces, it is possible to define a preferred class of mappings, known as tame maps. On the category of tame spaces under tame maps, the underlying topology is strong enough to support a fully fledged theory of differential topology. the girl who wears the tassel earringA Fréchet space is defined to be a locally convex metrizable topological vector space (TVS) that is complete as a TVS, meaning that every Cauchy sequence in converges to some point in (see footnote for more details).
