FO transductions between surface-embeddable graph classes
Prove that for surfaces $\Sigma$ and $\Gamma$ with $\Sigma\not\preceq\Gamma$, the class of graphs embeddable in $\Sigma$ is not FO-transducible from the class of graphs embeddable in $\Gamma$.
References
We conjecture that no more transducibility relations are present between those classes.
