Abstract:

In this paper, we explore the upper order-preservation of solution correspondence for parametric generalized vector equilibrium problems on chain-complete posets. In contrast to the previous results which mainly focus on the existence, topological continuity and algorithms, the order-preservation is a new subject for generalized vector equilibrium problems and it is useful for predicting the changing trend of solutions. Since our approaches are order-theoretic fixed point theorems and isotone selection theorems, neither convexity nor continuity is required for the mapping F.

Key words: Chain-complete poset, Generalized vector equilibrium problems, Fixed point theorem, Order-preservation
