In this paper,the concepts of two new variant of generalized nonlinear contractions in Menger probabilistic metric spaces are introduced.Without assuming any continuity or monotonicity conditions for three mappings,the uniqueness and existence of common fixed point of generalized nonlinear contraction mappings in probabilistic metric spaces are studied.Some new results are obtained,which generalize the current corresponding results in probabilistic metric spaces.Finally,an example is given to illustrate our main results.%在Menger PM-空间中引入了两个新的广义非线性压缩的概念.在不要求三个映射任何连续性和单调性的情况下,研究了三个映射在广义非线性压缩条件下公共不动点的存在唯一性问题,获得了一些新的结果,推广和改进了最近相关文献中的定理.最后,给出了主要结果的一个例子.
