| Jan 12, 2013 at 15:30 | comment | added | Ohad Asor | I got $-min(x,t)$ | |
| Jan 12, 2013 at 15:24 | comment | added | Carlo Beenakker | $g(x,t)={\rm max}(x-t,0)$ | |
| Jan 12, 2013 at 15:06 | comment | added | Ohad Asor | can you express it in terms of max/min? | |
| Jan 12, 2013 at 14:32 | comment | added | Carlo Beenakker | @Ohad: the product of $x-t$ and $\theta(x-t)$ is a continuous function with a discontinuous first derivative, $dg/dt=-\theta(x-t)$. | |
| Jan 12, 2013 at 13:11 | comment | added | Ohad Asor | so maybe I didn't get it.. doesn't Dirac and Heavyside discontinuous? | |
| Jan 12, 2013 at 12:47 | comment | added | Gerald Edgar | This $g$ is continuous. | |
| Jan 12, 2013 at 11:31 | comment | added | Ohad Asor | Hint: $g$ is continuous. | |
