I am currently looking at providing this user with a resource which may answer their question, however I cannot add this as a comment as I do not have enough reputation. I am not sure if I should post it as an answer as I fear it may not be well received by the community(for not being a proper answer) and also the fact that it is just a resource link. Should I post this as an answer? Is there any way in which I can show them this resource?(resource)

    $\begingroup$ WIth your permission, I can post it as a comment for you? Although, if the link answers the question, then you can simply answer the question. Do however make sure that it is not a "link-only" answer $\endgroup$ Nov 10, 2021 at 14:33
  • $\begingroup$ @CalvinKhor: I don't think it is necessary to post it as an answer, could you please post it as a comment. Thanks. $\endgroup$

    $\begingroup$ In general, link-only answers (even to questions asking for references) are bad. Ideally, an answer on Math SE should be self-contained, and should make sense even if the link "rots". In this case, where the poster is asking for references, a link is likely an appropriate part of a good answer, but such an answer should also contain a little bit of information about the linked resource (e.g. who is the intended audience? what can actually be found on the other side of the link? &c.). Basically, give a short (≈100 words) abstract. $\endgroup$

    $\begingroup$ I would add to @Xander’s comment that one should try to mitigate the effects of eventual link rot if possible. Eg If it is a paper or book, a proper citation is helpful. If it is unpublished lecture notes, I have found the author, title and even file name(!) to be useful for after the author retires and loses their webpage $\endgroup$ Nov 11, 2021 at 1:36
