abstract

We use the theory of $x-y$ duality to propose a new definition / construction for the correlation differentials of topological recursion; we call it "generalized topological recursion". This new definition coincides with the original topological recursion of Chekhov-Eynard-Orantin in the regular case and allows, in particular, to get meaningful answers in a variety of irregular and degenerate situations.

  1. Universal Correlators on Exponentially Ramified Spectral Curves

    math-ph 2026-07 conditional novelty 6.0 of 10

    Generalized topological recursion extends to spectral curves with essential singularities by replacing residues at the essential point with residues at ordinary meromorphic points.

  2. Super volumes and KdV tau functions

    math.AG 2024-12 conditional novelty 6.0 of 10

    The generalized BGW KdV tau function is identified as a generating function for spin class intersection numbers with Ramond punctures, yielding a proof of the Stanford-Witten recursion for the deformed super volumes.
