The Weierstrass Function - University of California, Berkeley
math.berkeley.eduThe Weierstrass Function Math 104 Proof of Theorem. Since jancos(bnˇx)j an for all x2R and P 1 n=0 a n converges, the series converges uni- formly by the Weierstrass M-test. Moreover, since the partial sums are continuous (as nite sums of continuous
The Stone-Weierstrass Theorem - Queen's U
mast.queensu.caStone in 1937, who realized that very few of the properties of the polynomials were essential to the theorem. Although this proof is not constructive and relies on more machinery than that of Bernstein, it is much more e cient and has the added power of generality.

A finite number of these neighborhoods cover K – so the set E must be finite. Theorem 2.41 Let {E ∈ Rk}. The following properties are equivalent: (a) E is closed and bounded.

However, Cantor never achieved his dream of holding a Chair of Mathematics at Berlin. It is believed that one of the main
