We characterize the subsets of the space \(\ell^\infty_n\) with continuous (lower semicontinuous) metric projection. One of the characteristic properties is the strict solarity of both the set and any nonempty intersection thereof with any support coordinate hyperplane.

空间\(\ ell ^ \ infty_n \)中具有连续度量投影的集合的特征

我们用连续(较低的半连续)度量投影来表征空间\(\ ell ^ \ infty_n \)的子集。特征属性之一是集合及其任何非空交点与任何支撑坐标超平面的严格日照度。
