We investigate S^3/Z_n partition function of 3d N = 2 supersymmetric field theories. In a gauge theory the partition function is the sum of the contributions of sectors specified by holonomies, and we should carefully choose the relative signs among the contributions. We argue that the factorization to holomorphic blocks is a useful criterion to determine the signs and propose a formula for them. We show that the orbifold partition function of a general non-gauge theory is correctly factorized provided that we take appropriate relative signs. We also present a few examples of gauge theories. We point out that the sign factor for the orbifold partition function is closely related to a similar sign factor in the lens space index and the 3d index.

  1. Meromorphic amplitudes from 3-dimensional supersymmetry

    hep-th 2026-06 unverdicted novelty 7.0 of 10

    Coon amplitude equals 3d N=2 half-index of XYZ model with boundary conditions; IR flow gives Veneziano amplitude, and elliptic completion of q^ST yields a meromorphic positive version.

  2. Flipping relation as a reduced star-star relation

    hep-th 2025-08 conditional novelty 5.0 of 10

    A specific limit of the star-star relation produces the flipping relation, and new flipping solutions are given in several gamma-function families.

  3. Ordinary limits of the hyperbolic hypergeometric integral identities

    hep-th 2024-12 reject novelty 3.0 of 10

    The paper asserts four ordinary hypergeometric integral identities as limits of hyperbolic ones, but supplies no derivations and admits most are already known.
