Not sure if this is related, but there appears to be something called

I see, so the limiting case that turns the inequality to an equality
is a sinusoid (or a corresponding complex exponential). If the signal
is band-limited, it must be a bounded sum of those, and the
derivatives must thus also be bounded sums of derivatives of those,
and your criterion will be satis

This is the so called "big O" notation.
f^(N)(t)=O(B^N) means (for a fixed t) that there is K such that
|f^(N)(t)|where f^(N) is the Nth derivative. Intuitively, "f^(N)(t) doesn't grow
faster than B^N"
