| Apr 20, 2011 at 3:28 | comment | added | Mariano Suárez-Álvarez | You'll find the theorem proved in Walter Rudin's book on distributions (Theorem 6.25) | |
| Apr 20, 2011 at 2:52 | comment | added | Jacques Carette | Great, that's the kind of theorem I was looking for. A reference would be most appreciated. | |
| Apr 20, 2011 at 2:45 | comment | added | Mariano Suárez-Álvarez | I mean: The derivative of a solution... | |
| Apr 20, 2011 at 2:40 | comment | added | Mariano Suárez-Álvarez | A solution is supported on the origin, so by a theorem (of Schwartz?) it is a finite linear combination of $\delta$ and it's derivatives. It is easy to check which, among these, which solve the equation. | |
