Wang–Zhou conjecture on residue reformulation of abstract topological recursion

Let $4\mathcal W_{g,n}4$ be the abstract $n$-point functions and let the abstract quantum field theory have spectral curve $4\mathcal C4$. Wang–Zhou's residue-reformulation conjecture. The abstract $n$-point functions can be modified as multilinear differentials on $4\mathcal C4$ so that the quadratic recursion can be reformulated using formal residues, and the realization of this recursion is equivalent to Eynard–Orantin topological recursion. This would provide an intrinsic geometric formulation of the abstract recursion; it is conjectural beyond the examples discussed in the paper.
