| Apr 10, 2018 at 15:06 | comment | added | Anixx | Then I get $\delta'(x)=\delta(x)$. Does not hold seemingly. | |
| Apr 10, 2018 at 15:02 | comment | added | Anixx | I am trying to insert m=0, r=1 but fail to see how this holds... | |
| Apr 10, 2018 at 14:55 | comment | added | Carlo Beenakker | quite frankly I don't know and I hoped to learn more from the source papers in Math.Student, which I have not been able to locate; (recent issues of this journal are online, but not older issues) | |
| Apr 10, 2018 at 14:43 | comment | added | Anixx | This is VERY interesting! But what is the second term? What does the $C$ and $\delta$ mean there? | |
