拟距离空间上一类集值映射的不动点定理

THE FIXED POINT THEOREM OF A CLASS OF SET-VALUED MAPPING ON QUASI METRICAL SPACE

在拟距离空间上引进了IIausdorff拟距离,讨论了其性质,建立了一类集值压缩映射的不动点定理,并证明了迭代逼近的收敛性。

In this paper ,IIausdorff qusi-distance on quasi metrical space is introduced,in addition to discussing its properties,the fixed point theorem of a class of set-valued Contraction mapping is set up and the convergence of iteration approximation is proved.
