comment Manipulating ergodic Markov chains in order to make them non-ergodic
@andry: I edited in response. Even a single edge is enough. If the original chain was ergodic, entering the absorbing state is inevitable.

comment Pseudo Proofs that are intuitively reasonable
I'm just curious: isn't it enough to show that the map is injective, and that $[0,1]^2$ is no smaller than $[0,1]$ because $[0,1] \times \{0\}$ is the same size?
