Monotonicity at a Point - Mathematics Stack Exchange
2018年6月19日 · For example, let's discuss the monotonicity of y = x² at x = 0. Using the definitions stated above, it is easy to observe that f(0+h) > f(0) and f(0-h) > f(0) but f'(0) = 0. Could someone please help clear the confusion, and tell what's the real definition for monotonicity at a point and also why the two above methods don't agree with each other?

$\begingroup$ I think the approach is fundamentally wrong; monotonicity is not a local property, you will not be able to define a satisfactory index by summing local contributions independently from each other, no mater what property you choose. $\endgroup$
real analysis - Monotonicity of function of two variables
2015年3月20日 · I have a function of two variables, which I wish to check for monotonicity in the entire function domain. I cant find any formal definition of increasing or decreasing function for multi variable case. Can anybody please guide? Thanks in advance.

2014年3月16日 · Kreps' textbook calls the same property "strict monotonicity". Jehle and Reny on the other hand agree with you definition of strict monotonicity. Finally I have seen papers referring to what you call "strict monotonicity" as "monotonicity". Quite a mess... $\endgroup$ –
