NUF(x) changes from 0 to ℵ₀ in (-x′/2,x′/2)For every definable x'.
but x′ ∉ (-x′/2,x′/2)
...and the same for each point > 0No. ∀n ∈ ℕ: 1/n - 1/(n+1) = 1/(n(n+1)) > 0 . NUF(x) cannot assume a value > 1 before it has assumed the value 1.
You (WM) incorrectly think that that's incorrect,The function NUF(x) is defined at every x. No further quantifier used.
I'd guess for the reason that
you incorrectly think that
a quantifier shift gives reliable results,
which it does not.
