The constraint set is the set of weakly effcient solutions of vector equilibrium problem, and perturbed by the perturbation of the criterion mapping to the vector equilibrium problem.展开更多

The following properties of them are proved.(i) An empirical model e is contextual if and only if R_C(e) > 0;(ii) the Ro C function R_C is convex, lower semi-continuous and un-increasing under an affine mapping on the set E M of all empirical models;(iii) e is non-contextual if and only if C(e) = 0;(iv) e is contextual if and only if C(e) > 0;(v) e is strongly contextual if and only if C(e) = 1. Also, a relationship between RC(e) and C(e) is obtained. Lastly, the Ro C of three empirical models is computed and compared. Especially, the Ro C of the PR boxes is obtained and the supremum 0.5 is found for the Ro C of all no-signaling type(2, 2, 2) empirical models.展开更多

文摘This paper establishes some suffcient conditions for the lower semicontinuity of the effcient solution mapping for the semi-infinite vector optimization problem with perturbations of both the objective function and the constraint set in normed linear spaces. The constraint set is the set of weakly effcient solutions of vector equilibrium problem, and perturbed by the perturbation of the criterion mapping to the vector equilibrium problem.
