Eigenvalues and eigenvectors of the second derivative
Hi, I was looking at Eigenvalues and eigenvectors of the second derivative, which you first edited in 2010. The material on that page is potentially relevant to my work, but I don't see any reference there. I wish to know the source for the results presented, especially from the discrete case section on, even if what's in the source is not entirely the same as what's on the wiki page. Thank you! Zxiong
