Frechet subdifferential

WebAbstract. A general mathematical programming problem in which the constraints are defined by multifunctions and depend on a parameter u, and the resulting value function m ( u) are considered. In the context of Banach spaces admitting equivalent Fréchet differentiable norms estimates for the generalized gradient ∂ m of m are established. Webx1 x2 f(x1)+gT 1 (z −x1) f(x2)+gT 2 (z −x2) f(x2)+gT 3 (z −x2) f(z) Figure 1: At x1, the convex function f is differentiable, and g1 (which is the derivative of f at x1) is the unique subgradient at x1.At the point x2, f is not differentiable. At this point, f has many subgradients: two subgradients, g2 and g3, are shown.
