Coderivatives at Infinity of Set-Valued Mappings with Applications to Optimization
本文定义了集值映射在无穷远处的余导数，建立了无穷远处的适定性性质和Mordukhovich准则，并给出了集值优化在无穷远处的最优性条件。
In this paper, the concept of coderivatives at infinity of set-valued mappings is introduced. Well-posedness properties at infinity of set-valued mappings as well as Mordukhovich’s criterion at infinity are established. Optimality conditions at infinity in set-valued optimization are also provided. The obtained results, which give new information even in the classical cases of smooth single-valued mappings, provide complete characterizations of the properties under consideration in the setting at infinity of set-valued mappings.
