What's the basic steps to show a set is denumerable? For example, $\mathbb{N}$ is denumerable.
A set $A$ is denumerable iff there exists (at least) one injective function $f:A\to\Bbb N$ and one injective function $g:\Bbb N\to A$.

If A is a denumerable set, and there exists a surjective function from A to B, then B is denumerable I am having some trouble solving the following homework question and some help would be greatly appreciated!! Q: Pr...
So, prove first that a set $S\ne \emptyset $ is denumerable if, and only if, there exists a surjection $f:\mathbb N \to S$. Now, if $g:A\to B$ is surjective and $A$ is denumerable, then there exists a surjection $f:\mathbb N \to A$.

Trying to show that set of all one-element subsets of a denumerable set is denumerable Let $A$ be a denumerable and put $X = \\{ B : B \subset A, \; \; |B| =1 \\} $. Then $X$ is denumerable: I know there is a bijecti...
On the other hand, if we take $A= \mathbb{Z}$ (the set of all integers), then $X$ is denumerable, but $g$ fails to surject onto $X$ (since, in particular
