Shape-preserving projections in low-dimensional settings and the q-monotone case

Abstract: In this setting, one can ask if S is left invariant under P , i.e., if P S ⊂ S. If V is finite-dimensional and S is a cone with particular structure, then the occurrence of the imbedding P S ⊂ S can be characterized through a geometric description. This characterization relies heavily on the structure of S, or, more specifically, on the structure of the cone S * dual to S. In this paper, шe remove the structural assumptions on S * and characterize the cases where P S ⊂ S. We note that the (so-called) q-monoton… Show more
