On the Coderivative of the Projection Operator onto the Positive Cone in Hilbert spaces
Le Van Hien, Nguyen Viet Quan
In this paper, we study the generalized differentiability of the metric projection operator onto the positive cone in Hilbert spaces. We first establish the formula for exactly com…
