Convergence of convex-concave saddle functions: applications to convex programming and mechanics

“…The choice of these two functions is in some sense minimal ( see [ 11 ], Section 2) to obtain convergence of saddle points as made clear in Section 4 of [10]. Other definitions have been proposed by Cavazutti [12], [13], Greco [14] ( see also Sonntag [15]). They all imply epi/hypo-convergence, but unduly restrict the domain of applications.…”
