... different if the ordering cone C is not pointed. So one must be careful when applying results in [4] for efficient points in the sense of (1) (as done in [2, p. 291]). For instance, Corollary 3.11 ... is efficient w.r.t. C in the sense of (2), while A has no efficient point w.r.t. C in the sense of (1). The set of efficient points of A w.r.t. C is called efficient set and denoted by...

... indeed a coloring of the corresponding underlying undirected graph, we get that gcn(G) ≤ ogcn(  G) for every orientation  G of every undirected graph G. Our main interest is in characterizing ... obtained by taking the vertices in increasing order). Since for each fixed vertex v ∈ V \ S, the probability that v is not a ν-successor of S is 1 − 2 −k and all these n − k events corresponding...

Common fixed point In this section, we investigate the existence of a common fixed point of a commuting family of order preserving mappings defined ... is in EC ( X ) . The above proof suggests that externally complete subsets are proximinal. In fact in [1], the authors introduced externally hyperconvex subsets as an example of proximin...
