关于拟范空间的Robinson-Ursescu定理

Robinson-Ursescu Theorem in Qusi-Normed Space

由凸集值映射的拟开性与拟Lipschitz性的内在联系,推导出拟范空间上集值映射的Robinson Ursescu定理。

Based on the connection between the quasi-open property and quasi-Lipschitz property for set-valued maps, the paper presents the forms of Robinson-Ursescu theorem, open mapping theorem and closed graph theorem in quasi-normed space.
