Abstract:By giving the concept of generalized guasi-weak commutativity of two selfmappings in a complete metric space, a common fixed point theorem for four selfmappings of a complete metric space are obtained under weaker conditions, which extend the known results, and at the same time, suitable examples are given.
Keywords:complete metric space  generalized quasi-weak commutativity  cauchy sequence
