| Abstract: | |||
| The paper is devoted to the description of the subdifferential of continuous sum of convex functions on a Banach space. Without any qualification condition, general sequential formulas are established@when the Banach space is separable. It is also shown how results under qualification condition in the literature can be derived from sequential ones. | |||
