Erratum: Weak Sharp Solutions of Variational Inequalities
Patrice Marcotte, Daoli Zhu · SIAM Journal on Optimization · 2000
Xuexiang Huang pointed out that the statement on line 5 of page 184 of [P. Marcotte and D. Zhu, SIAM J. Optim., 9 (1999), pp. 179--189] is invalid, and supplied an alternative proof of the inequality that appears on line 10. Here is a simple proof of this result due to an anonymous referee. The substitution starts at line 4 and ends at line 11.
