comment Return time for two independent one dimensional random walks
Yes. What I need is an explicit formula for $$ P(\tau_1 > k) $$

comment heuristic for expected number of visits random walk
Concerning the first comment, I see that, but then the question would be, what is the heuristic of the order of probability of reaching $x$ at all. Concerning the second comment, what do you mean by "noting that $R_n$ is $\Theta(\sqrt{n})$? I don't see how they are defined.

comment Bounding series with integrals
Yes sorry that was a typo. Yes I am looking for something more general than the integral test.
