I was intrigued by a question asked by another user, and although I didn't provide an answer, I engaged in externded chat with a user who did. He gave me lots of great advice, and gave me a lot of his time. The last comment ended in him pointing me in the right direction. I don't feel I can ask any more of him, since he has already helped me in understanding the problem so much already. Is it acceptable to pose a question based on my partital understanding of the problem, referencing his ideas and requesting clarification?

To clarify, a link to the question (and the numerous comments!) can be found here.

The comment I require clarification (and possibly extended explanation of) is:

that limit is the ratio of the coefficients of the eigenvector corresponding to the larger eigenvalue (which you can take at any $n≥216$ because it doesn't change beyond $216$). So compute ($a_{216},b_{216}$) for both strategies, decompose that with respect to the eigensystem of the recurrence matrix, and form the ratio of the coefficients corresponding to the larger eigenvalue.

I was not unfortunately able to achieve this.

    $\begingroup$ If your question meets the guidelines for a quality post on MSE, then I don't see why not. Your hesitance is a lack of understanding? $\endgroup$

  • $\begingroup$ @DonkeyKong My hesitance is twofold: 1) That I would be asking someone else (potentially) to clarify his comments. 2) That I would be asking a question based on a question that has already been officially answered. $\endgroup$

  • $\begingroup$ @DonkeyKong Since I have a lack of understanding in the area, I may be taking his comments out of context, which I know can be potentially contentious. $\endgroup$

    $\begingroup$ Thanks for clarifying. I think context might help, if the comments haven't been deleted? So long as you're not asking what a list of things some user told you mean, how they relate to one another, etc. (extremely broad and multi-faceted) and instead have some sort of particular problem you are focusing on, I would err on the side of saying your question would probably be alright. But I'm rather new here, might want to wait for a more experienced user. $\endgroup$

1 Answer 1


more noticeable this way. I asked joriki to email me, which he has done. If you do the same, I can forward each to the other and then you can directly email each other after that.

You can find my email address by looking at my profile here in MSE or by using my last name at http://www.ams.org/cml/

I don't know what time zone you are in. If you leave me a comment here I can also put my address for you in a return comment (if you are unable to find it through the CML or profile, that has happened sometimes). I just don't want that visible here for 24 hours straight.

    $\begingroup$ that really is very kind - of both you and joriki :) Will email you shortly. $\endgroup$
