{wiki=Denjoy–Riesz_theorem}

The Denjoy–Riesz theorem is an important result in real analysis, particularly in the context of functions of a real variable and integration. It deals with the conditions under which a function can be represented as being absolutely continuous and has implications for the behavior of functions that are Lebesgue integrable.
