In general,Banach space-valued Riemann integrable functions defined on[0,1](equipped with the Lebesgue measure)need not be weakly continuous almost everywhere.A Banach space is said to have the weak Lebesgue property if every Riemann integrable function taking values in it is weakly continuous almost everywhere.In this paper we discuss this property for the Banach space L1X of all Bochner integrable functions from[0,1]to the Banach space X.We show thatL1X has the weak Lebesgue property whenever X has the Radon–Nikodym property and X*is separable.This generalizes the result by Chonghu Wang and Kang Wan[Rocky Mountain J.Math.,31(2),697–703 (2001)]that L1[0,1]has the weak Lebesgue property.
