Approximation operators in optimization theory

Zeitschrift für Operations Research, 1981
Recently, new types of tangential cones such as the radial tangent cone, the hypertangent cone, the Clarke's tangent cone, and the set of directions in which a set is epi-Lipschitzian at a point have been introduced by Clarke, Hiriart-Urruty, and Rockafellar.
