Research Abstract

We have extended a duality theorem for the three-phase partition problem to two cases. One is the case that the optimal solution is degenerate, and the other is in higher dimensional space. We have given two types of discrete fixed point theorems. One is for monotone mappings and the other is for contraction mappings. We showed that the monotonicity is necessary in the two-person game. Further, we delete convexity assumption from discrete fixed point theorem based on Brouwer's fixed point theorem.
