Variational Analysis of Metric Projections onto Isotone Projection Cones via Coderivatives
Le Van Hien
In this paper, we study variational properties of the metric projection mapping onto isotone projection cones in finite-dimensional Euclidean spaces. We derive explicit formulas fo…

Regular Coderivative and Graphical Derivative of the Metric Projection onto closed Balls in Hilbert spaces
Le Van Hien
In this paper, we first establish a formula for exactly computing the regular coderivative of the metric projection operator onto closed balls centered at the origin…
