含没有开截口的对应的抽象经济的平衡

EQUILIBRIA OF Abstract ECONOMIES WITH CORRESPONDENCES WITHOUT OPEN SECTIONS

对具有无限多经纪人，具有无限维非紧策略空间和具有无开图或开下截口性质的选择和约束对应的非紧抽象经济，证明了某些新的平衡存在性定理。作为应用，由放松紧性和泛函的连续性，证明了某些拟变分不等式解的存在性定理。这些定理改进和推广了经济文献中的某些最近结果。

For the noncompact abstract economy with infinitely many agents,with infinitely dimensional noncompact strategy spaces and with preference and constraint correspondences without open graphs or open lower sections,some new equilibrium existence theorems are proved.As applications,some quasivariational inequalities are also obtained by relaxing the compactness and the continuity of functionals.These theorems impiove and generalize some recent results in economic literature.
