الوصف: | We investigate the relative computability of exchangeable binary relational data when presented in terms of the distribution of an invariant measure on graphs, or as a graphon in either $L^1$ or the cut distance. We establish basic computable equivalences, and show that $L^1$ representations contain fundamentally more computable information than the other representations, but that $0'$ suffices to move between computable such representations. We show that $0'$ is necessary in general, but that in the case of random-free graphons, no oracle is necessary. We also provide an example of an $L^1$-computable random-free graphon that is not weakly isomorphic to any graphon with an a.e. continuous version. Comment: 24 pages, 1 figure |
