| Abstract: | Zhang S S and others established some sufficient and necessary conditions and some sufficient conditions,on which the(32),(48),(64),(80) class contractive type mappings have a fixed point.Based on these theorems,introduced some new and more general contractive type mappings and given some sufficient and necessary conditions and some sufficient conditions,on which these new contractive type mappings have a fixed point.Obtained a new result,which improves and extends some relative results. |
