It has been proposed recently that the topological A-model string theory on local toric Calabi-Yau manifolds has a two parameter extension. Amplitudes of the two parameter topological strings can be computed using a diagrammatic method called the refined topological vertex. In this paper we study properties of the refined amplitudes under the flop transition of toric Calabi-Yau three-folds. We also discuss that the slicing invariance and the flop transition imply a simple formula for the homological sl(N) invariants of the Hopf link. The new expression for the invariants gives a simple refinement of the Hopf link invariant of Chern-Simons theory.

  1. Weyl symmetry in $(D_4,D_4)$ conformal matter on a circle

    hep-th 2025-05 conditional novelty 7.0 of 10

    Rank N (D4,D4) conformal matter on a circle is argued to have affine E8 Weyl symmetry in its brane webs, with 64 distinct sets of invariant Coulomb branch parameters for N ≥ 2.

  2. Thermodynamic limit for SO(2N) gauge theories with spinors/conjugate spinors

    hep-th 2026-07 conditional novelty 6.0 of 10

    The distinction between spinor and conjugate spinor matter in 5D SO(2N) gauge theories manifests as different boundary conditions on the Seiberg-Witten curve at O5-plane positions (w=±1).
