refinable (monotonely)

A map r from a compact metric space X onto a compact metric space Y is (monotonely) refinable if, for each positive number $\varepsilon $, there is a (monotone) $\varepsilon $-map f from X onto Y such that, for each x in X,

\begin{displaymath}
d\( f\( x\),r\( x\)\)< \varepsilon .
\end{displaymath}
