- What is infinity divided by infinity? - Mathematics Stack Exchange
I know that $\\infty \\infty$ is not generally defined However, if we have 2 equal infinities divided by each other, would it be 1? if we have an infinity divided by another half-as-big infinity, for

- infinity - What is the definition of an infinite sequence . . .
Except for $0$ every element in this sequence has both a next and previous element However, we have an infinite amount of elements between $0$ and $\omega$, which makes it different from a classical infinite sequence So what exactly makes an infinite sequence an infinite sequence? Are the examples I gave even infinite sequences?

- If $S$ is an infinite $\sigma$ algebra on $X$ then $S$ is not countable
6 Show that if a $\sigma$-algebra is infinite, that it contains a countably infinite collection of disjoint subsets An immediate consequence is that the $\sigma$-algebra is uncountable
