As somebody used to say:

Does research. Smokes. Battles administration. Smokes. Wishes he could stop battling administration so that he could have more time to do research. Smokes some more.

The same. Except I do not smoke.

comment Where does the second '1' appear?
Why did you accept (25 minutes after the question was asked) an answer which does not (as far as I can see) answer the question? That is, except if a complete solution is behind the wall where Brilliant asks to register...

comment For what values of $a > 0$ does $f(x,y)=(x^{2}+y^{a})^{-1} $ belong to $ L^{1}([0,1]^{2})?$
Why do you think $a=2$ should work?

comment Stopping time proof
I thought the OP already upvoted when they accepted this answer. Note that the explanation added at the beginning of the post points the flaw in the alleged proof that $\alpha$ is a stopping time, not why $\alpha$ is not a stopping time.

comment Question regarding Notes on Strong Markov Property
The question is not related to the "Strong Markov Property".

comment Question regarding Notes on Strong Markov Property
+1. One could add, to make sure the OP gets the point, that in the second setting the measures $P^x$ and $P^y$ are mutually singular for every $x\ne y$.

Any simple curve starting from (0,0) and going to infinity would do.
