【摘要】 提出了一类局部δ－Ｂｏｙｄ，Ｗｏｎｇ压缩映象，并证明了其存在唯一的不动点，且若空间是局部紧的或函数是单调不减的，则该不动点定理与Ｂａｎａｃｈ压缩映象原理是等价的．更多还原

【Abstract】 It is proved that there is a unique fixed point for every local δ-Boyd and Wong＇s mapping in the complete δ chained metric space.If the space is local compact one or φ is nondecreasing,this fixed point theorem is equivalent to Banach’s contraction mapping principle.更多还原
