Extremality, Stationarity and Generalized Separation of Collections of Sets
Hoa T. Bui, Alexander Y. Kruger
The core arguments used in various proofs of the extremal principle and its extensions as well as in primal and dual characterizations of approximate stationarity and transversalit…
The Radius of Metric Subregularity
Asen L. Dontchev, Helmut Gfrerer, Alexander Y. Kruger +1
There is a basic paradigm, called here the radius of well-posedness, which quantifies the "distance" from a given well-posed problem to the set of ill-posed problems of the same ki…
Hölder Error Bounds and Hölder Calmness with Applications to Convex Semi-Infinite Optimization
Alexander Kruger, Marco López, Xiaoqi Yang +1
Using techniques of variational analysis, necessary and sufficient subdifferential conditions for Hölder error bounds are investigated and some new estimates for the corresponding…
