| Jul 20, 2018 at 23:06 | comment | added | Suvrit | Nice answer! I was about to write an answer saying use the expansion of $\det(A+B)$ and notice that $e^{xy}$ is a totally positive kernel, when I just realized that the Andreieff identity is the integral version of the $\det(A+B)$ expansion...right? | |
