In your previous mail you wrote: A "Dictionary of mathematics" offers both definitions, first what you found f(x) > f(y) for x > y. Followed by the other definition f(x) >= f(y), where the first case would be called "strictly monotone". I vaguely recall that "strict" (in the German version), it's not completely unusual. => in French we have the same thing: "monotone" is either f(x) >= f(y) or f(x) <= f(y) for x > y and "strictement monotone" is either f(x) > f(y) or f(x) < f(y) for x > y.
