释义 | Stone-Weierstrass theorem [`stōn `vī·ǝr´sträs ´thir·ǝm] MATHEMATICS If S is a collection of continuous real-valued functions on a compact space E, which contains the constant functions, and if for any pair of distinct points x and y in E there is a function f in S such that f (x ) is not equal to f (y ), then for any continuous real-valued function g on E there is a sequence of functions, each of which can be expressed as a polynomial in the functions of S with real coefficients, that converges uniformly to g. |
