| Outline of Final Research Achievements |
In this study, we give several applications by using nonlinear scalarization methods for sets and proposed computational scheme for the scalarizing fucntions. This approach has been proposed in the previous study (research 21540121 supported by Grant-in-Aid for Scientific Research (C)). First, we clarified the inherited properties of the composite function of a monotonic scalarizing function and a sort of convex set-valued map systematically. As the results, we had several applications on certain generalization of Ricceri's nonlinear inequality to set-valued maps, alternative theorem for set-valued maps, and also we developed computational methods to evaluate the scalarizing functions and some construction of difference evaluation functions for fuzzy sets. Besides, we studied multicriteria two-persons zero-sum matrix games, algebraic properties of weak efficient solutions for sets, and hierarchical equilibrium problems including fixed-point problems.
