We make use of the Mangasarian Fromovitz regularity conditions and of the second-order Abadie regularity conditions. © 2012 Springer Science+Business Media, LLC.falseC(1,1) function | Minimax problem | Regularity conditions | Second-order optimality conditionsArticle15732878567-590March 201315arJournal6
