L. Thibault et D. Zagrodny, INTEGRATION OF SUBDIFFERENTIALS OF LOWER SEMICONTINUOUS FUNCTIONS ON BANACH-SPACES, Journal of mathematical analysis and applications, 189(1), 1995, pp. 33-58
This paper studies the lower semicontinuous functions f on Banach spac
es whose subdifferentials are not disassociated from f. Several condit
ions are given to ensure that two lower semicontinuous functions with
the same subdifferential are equal up to an additive constant. (C) 199
