We introduce Berge-modular games, and prove that the set of Berge equilibrium turns out to be a complete lattice. © 2015 World Scientific Publishing Company.EnglishBerge equilibriumBerge equilibrium in the sense of ZhukovskiiBerge-modular gamesFixed point theoryGames with strategic complementaritiesSupermodularityArticle10.1142/S02191989155000731793-6675
