We obtain an explicit expression for the number of ramified coverings of the sphere by the torus with given ramification type for a small number of ramification points, and conjecture this to be true for an arbitrary number of ramification points. In addition, the conjecture is proved for simple coverings of the sphere by the torus. We obtain corresponding expressions for surfaces of higher genera for a small number of ramification points, and conjecture the general form for this number in terms of a symmetric polynomial that appears to be new. The approach involves the analysis of the action of a transposition to derive a system of linear partial differential equations that give the generating series for the desired numbers.

  1. Phases in WLZZ Matrix Models

    hep-th 2025-07 conditional novelty 6.0 of 10

    For WLZZ two-matrix models, integration contours describe only a finite-N subspace of Ward identity solutions, and the full solution space is recovered only in the N-to-infinity limit.

  2. On Hamiltonians for Kerov functions

    hep-th 2019-08 conditional novelty 6.0 of 10

    The paper constructs naive commuting Hamiltonians for Kerov functions using the Kostka-Kerov matrix and proves the exponential Ruijsenaars shape cannot be lifted beyond the Macdonald locus.

  3. Non-commutative creation operators for symmetric polynomials

    hep-th 2025-08 unverdicted novelty 5.0 of 10

    Non-commutative creation operators B̂_m are built for symmetric polynomials in matrix and Fock representations of W_{1+∞} and affine Yangian algebras.
