摘　　要：在b度量空间中,提出名为LS型循环映射的新循环映射,在适当的假设条件下,研究LS型循环映射不动点的存在性与唯一性,得到了LS型循环映射不动点的存在唯一性定理.In b-metric spaces,a new kind of cyclic mapping was proposed,which was called LS-type cyclic mapping.Then,the existence and uniqueness of the fixed point of LS-type cyclic mapping was studied under appropriate assumptions,and the existence and uniqueness theorem of LS-type cyclic mapping was obtained.
