A Judgment Mode of Convergence or Divergence of Positive Sign Series

ZHOU Xia(Department of Mathematics,Neijiang Teachers College,Sichuan Neijiang,641112)  
Because of neither exist the Positive sign series of the slowest speed of convergence nor exist the Positive sign series of the slowest speed of divergence,So we can always find the new Positive sign series which is the slower speed of convergence or divergence than the former one,and acquire new judgment methods via them.This paper start with judging the convergence of Positive sign series,then establishes an appropriate judgment mode of convergence or divergence of Positive sign series by so many methods.
