 Sep 5 comment Proving that $X_n$ is (or is not) a Markov Chain @AndreaColonna What are you implying about the answer? Sep 4 comment Proving that $X_n$ is (or is not) a Markov Chain It just occurred to me that I might try making a table of all differing values x_n+1 can assume given x_n at a certain value. Sep 4 accepted How to show that the $k$th return to $y$ is a stopping time Sep 4 comment How to show that the $k$th return to $y$ is a stopping time So you mean that the event that $T_y^k$ is greater than $n$? If so, I understand thank you Sep 4 asked Proving that $X_n$ is (or is not) a Markov Chain Sep 4 comment How to show that the $k$th return to $y$ is a stopping time Sorry, I'm new to Markov chains, can you clarify what you mean by this?

The body is a typo. I mean the $\gcd(ab,n) = 1$ Aug 31 comment Proving that $a,n$ and $b, n$ relatively prime implies $ab,n$ relatively prime Well...this is embarrassing. Thanks!
