关于Dirichlet和Abel判别法的必要性注记

The Necessary Notes of Dirichlet and Abel Decision Method

文[1 ] 证明了无穷级数中的Dirichlet和Abel判别法的必要性 ,提出了这种必要性在函数项级数、广义积分中同样成立 .本文证明了Dirichlet、Abel判别法在函数项级数、广义积分中充要条件的正确性 .

Proving the necessity of Dirichlet and Abel decision method in infinite series, this paper proposes the necessity in function series and improper integral and proves the correctness of the necessary & sufficient condition of Dirichlet and Abel decision method in function series and improper integral.
