A few notes
Thank you for your contributions to mathematics articles. I have a few comments however.

First, I removed the proof you added to Green's function. Proofs are not that necessary in an encyclopedia, and I felt it was staying in the way of the exposition of the material.

Second, I removed the text you added to Sturm-Liouville theory. It is not true that Sturm-Liouville operators are always Hermitian, it all depends on the boundary conditions used. Also, I found the proof of the fact that the eigenvalues are then real unnecessary, that is a standard result for hermitian (self-adjoint) operators.

You can reply below this post if you wish to comment. Thanks. Oleg Alexandrov (talk) 03:28, 17 August 2007 (UTC)


 * Sorry, I think you are right, Sturm-Liouville operators are indeed Hermitian. I put your text back, at the end of the article, but I shortened it, since I believe those proofs are rather elementary but technical, and are not benefitting the article a lot.
