Some theorem states that there is no function with uncountably many strict extremal points.
For each , the set of all such that for all with is countable. This can be seen by noting that the set contains at most one element of the interval for each integer , and these intervals cover . The set of strict local maxima is a countable union of such sets, for example taking as ranges over the positive integers.
I wonder if the peaks of the Weierstass Function could be shown to have a bijection with
