On Second-Order Subdifferentials and Their Applications
SIAM Journal on Optimization, 2001The authors study second-order subdifferentials of extended-real-valued functions. The starting point is the second-order subdifferential introduced by the first author as the coderivative of the first-order subdifferentiable mapping. Beside this, a semiconvex version is introduced as the coderivative of the convexified first-order subdifferential ...

On the Subdifferentiability of Convex Operators
Journal of the London Mathematical Society, 1986Let Y be an ordered vector space. Every convex operator ranging in Y admits directional minorant at each point and in every direction of its domain space if and only if every decreasing lower bounded sequence in Y possesses an infimum. This result, combined with a theorem of M. M.

Approximations of Subdifferentials
2014In practice, the computation of subdifferential is not an easy task. In this chapter, we first consider some families of set-valued mappings that can be used to approximate subdifferentials. Then we define the concept of a discrete gradient that can be used as an approximation of the subgradient at a given point.

The properties of the weak subdifferentials
2010This paper deals with the weak subdifferentials. The properties of the weak subdifferentials are examined. It is showed that the weak subdifferential of a function having a global minimum is not empty.
