= Superposition theorem for Poisson point processes
{c}

The union of independent Poisson point processes with diffuse intensity measures $\mu_1,\ldots,\mu_m$ is a Poisson point process with intensity measure
$$
\mu_1+\cdots+\mu_m.
$$
On every finite collection of disjoint measurable sets, this follows by adding independent <Poisson distribution>[Poisson counts] and checking that the resulting counts remain independent.
