报告摘要：In this talk, the notion of generalized derivatives at infinity is introduced. Various calculus rules for this notion are established. The main well-posedness properties (the linear openness, the metric regularity, and the Lipschitz-like  continuity) at infinity as well as Mordukhovich's criterion at infinity are discussed. The obtained results are aimed ultimately at applications to diverse problems of optimization, such as optimality conditions, weak sharp minima, coercive properties and stability results. The talk is based on recent works in collaboration with Do Sang Kim, Nguyen Minh Tung and Nguyen Van Tuyen.
