On the characterization of compact Hausdorff X for which C(X) is
... algebraically closed, one knows a configuration which cannot be a part of any space which has a closed function algebra. It turns out that the two configurations mentioned above come very close to giving a complete answer to the problem. Another lemma which sheds a great deal of light on the problem ...

... Elementary arguments are employed in this paper to give a characterization of the set of primes and to extend this set to a larger one whose elements are defined by a single property: we show that a positive integer is either a prime or a power of 2 if and only if such an integer cannot be expressed ...
