We prove strengthened and unified forms of vectorvalued versions of the StoneWeierstrass theorem. This is possible by using an appropriate factorization of a topological space, instead of the traditional localizability.
Our main Theorem 7 generalizes and unifies number of known : The theorem book. This paper extends a version of the StoneWeierstrass theorem to more general C*algebras. Namely, assume that A is a unital, not necessarily separable, C*algebra, and B is a C*subalgebra Author: Kung Fu Ng. The classical WeierstrassStone Theorem is obtained as a corollary, without Zorn s Lemma.

DEUTSCH, An elementary proof of the StoneWeierstrass theorem, Proc. Amer. Math. Soc. 81 (), Let A be point separating unital subalgebra of C(T) where T is a compact metric space. For each bounded function f:T→R which is continuous on the complement of a meagre subset of T there exists a sequence (wn) of elements of the algebra A such that the sequence (wn) convergence uniformly to the function f on each compact subset of the interior of the continuity points of the function f.

Karl Theodor Wilhelm Weierstrass (German: Weierstraß [ˈvaɪɐʃtʁaːs]; 31 October – 19 February ) was a German mathematician often cited as the "father of modern analysis".Despite leaving university without a degree, he studied mathematics and trained as a school teacher, eventually teaching mathematics, physics, botany and gymnastics.

Let C(S; E) be the linear space of all Evalued continuous functions ƒ on S with the uniform norm ƒ = sup{ƒ(t); t ∈ S}.
When E = R, the WeierstrassStone Theorem describes the uniform closure of a subalgebra of C(S; R).We extend this classical result in two ways: we admit vectorvalued functions and.

The upside is that we could prove the Weierstrass Approximation Theorem as a consequence of the WeierstrassStone Theorem.) So obviously, this particular theorem is interesting and very useful for practical reasons: it allows one to approximate any complex valued continuous function by a sequence of polynomials to any desired accuracy.
For the second part, I don't have any idea how to use the Stone Weierstrass Theorem to prove it. I have never used this theorem before in solving problems, so I appreciate if.

This book is meant as a text for a first year graduate course in analysis. Any standard course in undergraduate analysis will constitute sufficient preparation for its understanding, for instance, my Undergraduate Anal ysis. I assume that the reader is acquainted with.

So, is there any text introducing this theorem in full strength. And is the proof quite elementary so that an undergraduate (just like me) can understand the proof.
Weierstrass–Stone Theorem If X is any compact space, let A be a subalgebra of the algebra C (X) over the reals R with binary operations + and ×. Then, if A contains the constant functions and separates the points of X (i.e., for any two distinct points x and y of X, there is some function f in A such that f (x) ≠ f (y)), A is dense.
