摘要
对正项级数的达朗贝尔判别法作了推广,提出并证明了p-达朗贝尔判别法,扩大了其使用范围.进一步利用数列和子列的收敛关系,证明了其与柯西判别法之间的关系.最后通过例子对p-达朗贝尔判别法进行了验证.
D＇Alembert discriminance is promoted to the p-DPAlembert discrimination for positive series, and then the corresponding p-D＇Alembert discrimination is proved. Further convergence relation of sequence and its sub-sequence is used to discuss the relationship between the discrimination and Cauchy discrimination. Finally, some examples of this method are Verified.
