“…We view (d), which can be generalized to certain non-planar graphs, as the emergence of the Euler characteristic (which is a global topological invariant). This has been shown by some of us recently [34] via computations of multipartite information on a plane, which capture the Topological Entanglement Entropy (TEE) [19,23] of a topologically ordered phases of quantum matter [52,53,54]. We also note that a recent work [46] has shown that the multipartite information between D + 1 partitions of a D-dimensional non-interacting Fermi gas is proportional to the Euler characteristic of the D-dimensional Fermi volume.…”

“…Remark 2.12. We have found that the alternative sum of the count D j (C n ), denoted by β Cn (−1) for any planar embedding of C n , is proportional to the n-partite information and topological entanglement entropy [34]. The cycle graph is crucially related to the topological entanglement entropy measure of a collection of subsystems arranged in an annulus.…”
