Abstract:

In this note a question posed by J. D. Bryant and L. F. Guseman, Jr. is answered. It is shown that for dense subsets of finite dimensional Banach spaces, the iterative test being conclusive and the contractive extension property are not equivalent. If $(X,d)$ is a complete locally compact and chainable-metric space, a characterization of these dense subsets for which the iterative test is conclusive is given.
