Ioffe, A.
Typical convexity (concavity) of Dini-Hadamard upper (lower) directional derivatives of functions on separable Banach spaces. (English)
[J] J. Convex Anal. 17, No. 3-4, 1019-1032 (2010). ISSN 0944-6532

The author extends and amplifies a few results on the typical properties of Dini--Hadamard-type directional derivatives. The modifications deal with expanding the class of functions under consideration and specifying the qualification of typicality.
