Hello,
Let X and Y be two spaces equipped respectively with two metrics [itex]d_1[/itex] and [itex]d_2[/itex], and let's consider a mapping [itex]f:(X,d_1)\rightarrow(Y,d_2)[/itex]
How can I formalize the fact that for any point x in X, all the points that are "very close" to x (respect to the metric [itex]d_1[/itex]) must be mapped into points in Y that are "very close" to f(x) (with respect to the metric [itex]d_2[/itex]).
Thanks!
