"WebFor the topology, induced by a metric, a function f is continuous if for every x and every ϵ, there exists such a δ that for all y, d ( x, y) < δ implies d ( f ( x) − f ( y)) < ϵ. This is the standard definition of continuity known from mathematical analysis. Using tools from analysis, it is not hard to show that f is, indeed, continuous. Share " - Continuity topology

That means that it depends uniquely on the topology you put on the (topological) space; indeed, the most general definition of continuity between topological spaces is the following: a map f: X Y between topological spaces is continuous is and only if for every open set V ⊆ Y the set f − 1 ( V) is open in X.

Webtopology, branch of mathematics, sometimes referred to as “rubber sheet geometry,” in which two objects are considered equivalent if they can be continuously deformed into one another through such motions in space as bending, twisting, stretching, and shrinking while disallowing tearing apart or gluing together parts.
