| Jul 30, 2022 at 18:39 | comment | added | Bob Stewart | The above PDE is the 2017 corrected equation which has a + sign for the last term. The excellent analysis given below is not valid because it was based upon the previously posted incorrect 2014 version of the PDE with a - sign in font of the last term (my mistake). So according to @Willie Wong, the above corrected PDE may have a nontrivial solution (subject to more analysis), and I believe it does have only one solution although I have not yet found it. I will post the answer if and when I find it. | |

I discovered a sign error, thus the old trivial solution is no longer valid, and the third condition is modified.

| Sep 4, 2014 at 6:10 | comment | added | Joonas Ilmavirta | Do you know if the PDE should be the Euler-Lagrange equation for some minimization problem? That might help. | |
