Abstract

We introduce the area balance function associated to a Lebesgue integrable function f : [a, b] → C by ABf (a, b, ·) : [a, b] → C, ABf (a, b, x) := x f (t) dt − x l (t) dt . a We show amongst other that, if f : I → C is an absolutely continuous function on the interval I and [a, b] ⊂ ˚I, where ˚I is the interior of I and such that fl is of bounded variation on [a, b] , then we have the inequality...
