Galois-orbit conjecture for rational intrinsic data

About 13 years old · traced to

Fix a set of fusion rules, and consider all modular categories having those fusion rules. For a modular category C\mathcal C, let ID⁡(C)\operatorname{ID}(\mathcal C) denote its fusion rules, SS- and TT-matrix data, RR-matrix eigenvalues, and Frobenius–Schur indicators; its rational intrinsic data are Q∩ID⁡(C)\mathbb Q\cap\operatorname{ID}(\mathcal C). Galois-orbit conjecture. The rational intrinsic data arising from all modular categories with the fixed fusion rules are in one-to-one correspondence with the Galois orbits. The source also notes that rational intrinsic data are invariant under Galois twists; the asserted correspondence itself is not resolved in the supplied text.
