High order tangent vectors to sets with applications to constrained optimization problems
Valentin V. Gorokhovik
We introduce an extended tangent cone of high order to a set and study its properties. Then we use this local approximation for deriving high-order necessary conditions for local m…
Regularly abstract convex functions with respect to the set of Lipschitz continuous concave functions
Valentin V. Gorokhovik
The goal of the paper is to study the particular class of regularly -convex functions, when is the set of…
Minimal convex majorants of functions and Demyanov--Rubinov super(sub)differentials
Valentin V. Gorokhovik
The primary goal of the paper is to establish characteristic properties of (extended) real-valued functions defined on normed vector spaces that admit the representation as the low…
Saddle representations of positively homogeneous functions by linear functions
Valentin V. Gorokhovik, Marina Trafimovich
We say that a positively homogeneous function admits a saddle representation by linear functions iff it admits both an inf-sup-representation and a sup-inf-representation with the…
