Subdifferentials at infinity and applications in optimization
Do Sang Kim, Minh Tung Nguyen, Tien Son Pham
In this work, the notions of normal cones at infinity to unbounded sets and limiting and singular subdifferentials at infinity for extended real value functions are introduced. Var…

Clarke's tangent cones, subgradients, optimality conditions and the Lipschitzness at infinity
Minh Tung Nguyen, Tien-Son Pham
We first study Clarke's tangent cones at infinity to unbounded subsets of We prove that these cones are closed convex and show a characterization of their interiors…
