Given a sequence, how does one prove that the associated series in convergent or not, in a given norm? For example,
[tex]\sum_{k=0}^{\infty}a_{k} [/tex] in [tex]||\cdot|| [/tex]
The process to do this is not in my book; I'm told how to determine whether a series is cauchy, but I'm not sure how to use that to show it's convergent.
