| Apr 29, 2017 at 19:51 | comment | added | keej | I was having trouble computing the spectral measure of $(L-z)^*(L-z)$, however. Is that still easy? And fair enough, I posted here because the only other references to Brown measure I could find were in research papers. I just posted in stackexchange. | |
| Apr 29, 2017 at 17:26 | comment | added | Christian Remling | The spectral measure of $L$ wrt $\delta_0$ is Lebesgue measure on $S^1$. Using this as your starting point, it should be possible to work everything out explicitly. I believe your question would have been better suited for math.stackexchange.com | |
| Apr 29, 2017 at 17:17 | comment | added | Christian Remling | To address my own comment, I guess what you're saying is that $\nu_z$ is defined as the spectral measure $d\|E(x)\delta_0\|^2$ of $\delta_0$ ("the spectral measure," meaning a positive measure on $\mathbb C$, is not unambiguously defined)? | |
