摘要
本文讨论了多值函数的逼近问题，得到关于非凸值多值函数的两个逼近定理，Ｃｅｌｌｉｎａ逼近定理和 Ｄｅ Ｂｌａｓｔ－Ｍｙｊａｋ逼近定理被作为推论重新得到，最后，作为应用，证明了一个抽象经济模型的均衡存在性定理．
In this paper, problems about approximation of multifunctions are discussed, two approximation theorems for nonconvex-valued multifunctions are obtained, Cellina approx-imation theorem and De Blasi-Myjak approximation theorem are given again as the corollaries. As an application, an equilibrium existence theorem of abstract economy is proved.
