Abstract:
We study Tychonoff spaces $X$ with the property that, for all topological embeddings $X\to Y $, the induced map $C(Y) \to C(X)$ is an epimorphism of rings. Such spaces are called \good. The simplest examples of \good spaces are $\sigma$-compact locally compact spaces and \Lin $P$-spaces. First countable spaces must be locally compact in order to be \good. However, a ``bad'' class of \good spaces is exhibited whose pathology settles, in the negative, a number of open questions. Spaces which are not \good abound, and some are presented. Many open questions remain.
