Abstract: Let *F* be a differentiation basis in , i.e., a family of measurable sets *S* contracting to 0 such that , where is the Hardy-Littlewood maximal operator. For , we let be the complement of the Lebesgue set of *f* relative to *F*, and we show that has -capacity 0, where is a capacity associated with in much the same way as the Bessel capacity is associated with .
