5 дек. 2019 г. · A different approach: g(x)=13x−2/3 is integrable on [−1,1] and f(x)=∫x0g(t)dt. This is enough to say that f is absolutely continuous. Show that f(x)=√x for 0≤x≤1 is absolutely continuous on [0,1] Lipschitz and Absolute Continuity - Mathematics Stack Exchange Proof that √x is absolutely continuous. - Math Stack Exchange f - is absolutely continuous on - [ - 0, x - ] - , bounded variation ...
