The Gauss Index Discrimination Method of Positive Term Series

JI Xiao-long,WANG Rui-li(Jiyuan Vocational and Technical College,Foundamental Science Department,Jiyuan Henan 454650,China)  
Based on the Gauss discrimination method of positive term series,this paper defines the Gauss index G=lim[n ln(an/an+1)-1]ln n of Positive number sequence an and gains the Gauss index discrimination method of positive term series.What′s more,it is proved that the Gauss index discrimination method is on the basis of the J.D′ Alembert′s criterion, the A.L.Cauchy′s criterion and the Gauss criterion and the Bertrand′s criterion etc.through calculating all the Gauss index discrimination methods.
