摘要
本文在概率度量空间中讨论了两类映象不动点存在的充分必要条件,本文结果,附带解决了 Rhoades[1]所提出的未解决的问题4。
The paper discusses some sufficient and necessary conditions of the exis- tence of fixed point for two kinds of mappings inprobabilistic metric spaces. As application consequently,Open Question 4 suggested in Rhoades [1] is an- swered.
