Faces in the unit ball of the dual of \({\mathcal L}({\mathbb{R}}^ n)\)
Let E be the n-dimensional Euclidean space. In the paper the dimension of the faces (extremal subsets) of the unit ball of the dual space of the space of linear operators from E into E is considered. This unit ball turns out to be stable in the sense presented in [\textit{S. Papadopoulou}, Math. Ann. 229, 193-200 (1977; Zbl 0339.46001)].
