单词	function space
释义	function space A general term relating to a space of functions between two given sets X and Y. If the codomain has further structure (e.g. if Y = R), then functions can be pointwise added and multiplied, forming an algebra, and given a partial order. If the domain X is a topological space, then the space C(X) of bounded, continuous functions real-valued functions on X can be made into a normed vector space with . For vector spaces V and W, then Hom(V,W), denoting the space of linear maps from V to W, is a vector space itself. See also C0, C1, C∞, Cω, Lp.
