Abstract
A non-expansive mapping needn't have fixed points on metric spaces.Ljubomir investigated a class of non-expansive type mappings and fixed point's theorem.In this paper,a new class of non-expansive type mappings and fixed points theorem were given.Meanwhile,the fixed points theorem about the new mappings was proved.
