設(shè)H是一實(shí)Hilbert空間,〈·,·〉和‖·‖分別表示其上的內(nèi)積和范數(shù),C是H的非空閉凸子集.G:C×C→R是二元均衡函數(shù),R為實(shí)數(shù)集,φ:C→R為實(shí)函數(shù),A:H→H是非線(xiàn)性映像,F(xiàn)(T)是映像T的不動(dòng)點(diǎn)之集.
近年來(lái),黏性迭代逼近算法被應(yīng)用到凸優(yōu)化問(wèn)題,單調(diào)包含和微分方程等領(lǐng)域,受到越來(lái)越多研究者的關(guān)注[1-7].依據(jù)文獻(xiàn)[8]的研究思想方法,本文在Hilbert空間的框架下,定義了一種新的黏性迭代算法,用以逼近廣義混合均衡問(wèn)題的解集與無(wú)限族k-嚴(yán)格偽壓縮映像的不動(dòng)點(diǎn)集的公共元.在適當(dāng)條件下,證明了由算法生成的迭代序列的收斂性.其結(jié)果改進(jìn)和推廣了該領(lǐng)域內(nèi)某些最近結(jié)果.
