Currently there are 131 questions with the tag eigenvalues. This includes both questions around the finding of eigenvalues and eigenvectors of a matrix as well as of a differential operator (and associated eigenfunctions).

As someone who is interested in questions of the latter type but not of the former, I'd like to split the tag into the two parts. I'd suggest eigenvalues and eigenfunctions personally, but open to suggestions (or telling that the tag shouldn't be split).

  • 131 questions is not very many, I believe, and that number can be reduced to 90 by excluding questions also tagged as [differential-equations]. I reasonable question, though (+1). – bbgodfrey Nov 18 '18 at 6:21
  • Yes, I guess that all those which are tagged as both [eigenvalues] and [differential-equations] are what I'm interested in. – KraZug Nov 18 '18 at 9:30

    @KraZug which means you don't really need a separate tag :-), do you? – Kuba Nov 20 '18 at 20:27
  • @Kuba, well, is there a way to watch for the intersection of two tags? – KraZug Nov 20 '18 at 20:45

    I don't think so but I also don't think it is a reason for a new tag. Otoh I am just commenting here and will wait for more input from people interested in this topic more than me. – Kuba Nov 20 '18 at 21:11
