BILEVEL OPTIMIZATION PROBLEMS IN TOPOLOGICAL SPACES
In this paper, we introduce and study the bilevel optimization ::: problems in topological spaces without linear structure. For these problems, ::: we establish two models which are different in the feasible region setting of ::: lower-level problems. Some new existence results are obtained in rather weak ::: conditions. These theorems improve and generalize the corresponding results ::: of bilevel optimization in the literatures.
