摘　　要：在Hilbert空间中,用Fan-KKM定理导出了广义平衡问题的辅助问题的解的存在性和唯一性,讨论了寻找广义平衡问题和一族非扩张映象的公共不动点集的迭代序列,证明此序列强收敛于这两个集合的公共元.本文结论改进了一些近期结果.By using the Fan-KKM lemma,the existence and uniqueness of solution of the auxiliary problem for GEP is derived. A iterative method for finding a common element of the set of solution of a generalized equilibrium problem and the set of fixed points for an infinite family of nonexpansive mappings in a Hilbert space is induced. Under suitable conditions a strong convergence theorem is proved. The results presented in the paper extend and im proved some recent results.
