| Abstract: | In this paper we approach the study of the subdifferential of the closed convex hull of a function and the related integration problem without the usual assumption of epi-pointedness. The key tool is, as in Hiriart-Urruty et al. (2011) 7], the concept of ε-subdifferential. Some other assumptions which are standard in the literature are also removed. |
