| Outline of Final Research Achievements |
In this research, we deal with zero point problems of maximal monotone operators which have applied to other research fields such as engineering, economics, and the others. We investigated the proximal point algorithms for finding their problems. In particular, we focused on the concept of the metric projection and study the nonexpansivity of the metric projection, that is a mapping of type (P). We proposed algorithms for finding a solution of the zero point problem and the fixed point problem which related to the metric projection. We also proposed algorithms for finding a fixed point of a mapping of type (R), which is related to a mapping of type (P).
