comment Show Green's function solves Poisson's equation
$H$ is called a fundamental solution. You might want to take a look at Fritz John book. To prove it classically, you'll have to separate the singularity at $x_0$ from the rest of the integral (using a ball of radius $\epsilon$), and then investigate the behavior in the limit. I've used the argument here

Studying the Burger's equation, as @user88595 suggest, will not only help you to derive the solution, but also to understand how it behaves.
