real analysis - Definition of convergence of sequences
I know what a sequence is, I know what convergence mean, I know what complex numbers, natural numbers etc. mean and as I know, epsilon is just a variable like x and y for instance. But I don't understand the definition and it's driving me a bit insane why the authors of the book don't explain it in a way so that a person who are new to this ...
What is the difference between convergence of a sequence and ...
2014年11月23日 · You can identify a series with the sequence of its partial sums: $$ S_n = \sum_{k=1}^n a_k. $$ So everything you know about sequences can be applied to series, and vice-versa.

My task is to write a precise mathematical statement that "the sequence $(a_n)$ does not converge to a number $\\mathscr l$" So, I have my definition of a convergent sequence: "$\\forall\\varepsilon&...
Proving that a convergent sequence has a unique limit
Is it not known (prior to uniqueness of limits) that $\lim_{n\rightarrow \infty}0=0$, and the limit is unique in the case of a constant sequence? $\endgroup$ – Wrath CC Commented Jan 9, 2017 at 0:21
general topology - Convergence in a Topological Space
$\begingroup$ Thanks for your help! and I'm sorry, what I meant was a sequence in a topological space. I know the examples that you showed me exhibit a non-convergence sequence, but I don't quite see how that relates to the idea of the open neighborhoods. $\endgroup$ –
real analysis - Convergence of a Specific Recursive Sequence ...
2024年11月29日 · I'm pretty sure that means that if the sequence does converge, it must converge to $1$, but "I'm pretty sure" isn't much of a proof. I don't see any way to find an explicit form for the sequence (and I suspect there isn't one). The sequence isn't monotonic, since it oscillates above and below $1$.
convergence of a sequence- choosing epsilon and understanding
A sequence $(𝑎_𝑛 )$ converges to $𝑐$ if for every $\epsilon>0$, there exists an index $𝑁$ so that, for all $𝑘≥𝑁$, $|𝑎_𝑘−𝑐|<𝜖$. if we pick really large epsilon, it is always going to work.
