| Sep 8, 2016 at 22:18 | comment | added | Gandalf Lechner | There are two obvious solutions: $L=0$ and $L=T$. Do you ask for invertible $L$? In that case, you only have $L=T$, as a consequence of your equation for $m=1$. The equation for $m=2$ tells you that the spectrum of $L$ is contained in $\{0,-1,1\}$. To proceed from here, it would be helpful to know more about $L$, such as normality. | |
