| Nov 1, 2016 at 17:42 | comment | added | Neal | I wrote down an example here of why the eigenvalues and eigenfunctions of the Laplacian are difficult to compute analytically. (I would also note that eigenvalues of finite-dimensional operators are roots of polynomials, which are also nontrivial to compute.) | |

| Sep 28, 2013 at 18:23 | comment | added | András Bátkai | I did not vote here, but I think what you write seems to be known for the OP. The exact eigenvalues and eigenfunctions were the question, maybe this was the problem. | |
| Sep 28, 2013 at 17:48 | comment | added | user36539 | I think this answer is correct.. Can someone explain to me where is the error, please ? | |
