Abstract:
We prove that there is a natural injective correspondence between the maximal ideals of the ring of analytic functions on a real analytic set $X$ and those of its subring of bounded analytic functions. By describing the maximal ideals in terms of ultrafilters we see that this correspondence is surjective if and only if $X$ is compact. This approach is also useful for studying the orderings of the field of meromorphic functions on $X$.References
