I am using Ross: Elementary Analysis 2nd Edition.
I do not know how to interpret sets of this type:
" If $L=\limsup s_n \neq \infty$ then for every $\alpha >L$ the set $\{n: s_n > \alpha \}$ is finite."
Generally, how do you interpret sets like $\{n: s_n > \alpha \}$?
Does this set include as its the element every index, $n$, of every term in the sequence $(s_n)$ greater than $\alpha$? i.e. The elements of the set will just be natural numbers...?
