A sequence of partially ordered sets whose homomorphism densities converge has a limit representable by a kernel on an ordered probability space. The standard representation conjec…

Let $W$ be a kernel, or more generally a function, from ${\mathcal S}^2$ to $[0,1]$, where ${\mathcal S}$ is a probability space. Two points $x_1,x_2\in{\mathcal S}$ are twins if…
