改进了阿泽等人[非线性分析]中引入的变分方法。49(2002)643-670]中,我们给出了定义在完备度量空间上的下连续函数的所谓全局和局部误差界的存在性的特征。因此,我们提供了一个系统的和综合的方法的主题,强调凸函数的特殊情况下定义的任意Banach空间(细化抽象部分的阿泽和Corvellec [SIAM J. Optim . 12(2002)913-927],以及完备度量空间之间闭图多函数的局部度量正则性的表征。
Refining the variational method introduced in Aze et al. [Nonlinear Anal . 49 (2002) 643-670], we give characterizations of the existence of so-called global and local error bounds, for lower semicontinuous functions defined on complete metric spaces. We thus provide a systematic and synthetic approach to the subject, emphasizing the special case of convex functions defined on arbitrary Banach spaces (refining the abstract part of Aze and Corvellec [SIAM J. Optim . 12 (2002) 913-927], and the characterization of the local metric regularity of closed-graph multifunctions between complete metric spaces.
