Let X be a Banach space, C be a nonempty closed convex set and \(\sigma _C\) be the support function of the set C. In this work, we give some necessary and sufficient conditions for the set C to satisfy \(\mathrm {int}(\mathrm {dom}\sigma _C)\ne \emptyset \), which enable us to study the Frechet and Gateaux differentiability of support function on the set C.

关于支持函数的微分的一些注意事项

X为Banach空间,C为非空封闭凸集,\(\ sigma _C \)为集C的支持函数。在这项工作中,我们给出了满足C (\ mathrm {int}(\ mathrm {dom} \ sigma _C)\ ne \ emptyset \)的一些充要条件,这使我们能够研究Frechet和Gateaux集C上支持函数的可微性。
