Definitions
subdifferentiability
Noun
Mathematics, convex analysis: the quality or state of a function being subdifferentiable at a given point—that is, of possessing a non-empty subdifferential there; a generalization of classical differentiability.
Because of its subdifferentiability at zero, the convex function admits a linear subgradient that supports its graph at that point.
