| Apr 25, 2010 at 19:23 | comment | added | Jim Humphreys | Sorry, I was distracted by the header and didn't look far enough into the question. Some of my colleagues have been fond of sine-Gordon, but I'm an outsider. | |
| Apr 25, 2010 at 18:28 | comment | added | Qiaochu Yuan | Jim, Kaveh is talking about the sgn function, not the sin function. (That is, it's a pun on the sine-Gordon equation.) | |
| Apr 25, 2010 at 17:10 | comment | added | Kaveh Khodjasteh | I thought about that but sinh would scale like O(\phi) in the small limit while sgn(\phi) scales like O(1). Thanks for the idea of scaling though. | |
| Apr 25, 2010 at 16:20 | comment | added | Steve Huntsman | Rescale $x$, then rescale $t$ identically so the derivatives both get the same constant multipliers. The constants that pop out don't affect the signum, so you can rescale $\varphi$. So this is a kind of scaling limit of sinh-Gordon. | |
