This paper is the second in a series of five that together prove the geometric Langlands conjecture. Our goals are two-fold: (1) Formulate and prove the Fundamental Local Equivalence (FLE) at the critical level; (2) Study the interaction between Kac-Moody localization and the global geometric Langlands functor of ref. [GLC1]. This paper contains an extensive Appendix, whose primary goals are: (a) Development the theory of ind-coherent sheaves in infinite type; (b)Development of the formalism of factorization categories.

Discussion (0). Continue with ORCID to comment.

  1. A proof of Dolbeault geometric Langlands for $\mathrm{GL}_2$ with reduced spectral curves

    math.AG 2026-02 conditional novelty 8.0 of 10

    For GL_2, the Dolbeault geometric Langlands equivalence is proved over the reduced-spectral-curve locus of the Hitchin base, using limit categories, the Arinkin sheaf, and Wilson/Hecke compatibility.

  2. The Dolbeault geometric Langlands conjecture via limit categories

    math.AG 2025-08 conditional novelty 8.0 of 10

    Limit categories are defined, proven compactly generated and semiorthogonally decomposed into quasi-BPS categories, then proposed as the correct automorphic side of the Dolbeault geometric Langlands conjecture.

  3. Parabolic geometric Eisenstein series and constant term functors

    math.RT 2025-07 conditional novelty 8.0 of 10

    This paper proves that parabolic Jacquet functors on Whittaker categories match restriction and Lie algebra cohomology of representations under the geometric Casselman-Shalika equivalence.

  4. Non-vanishing of quantum geometric Whittaker coefficients

    math.RT 2025-08 conditional novelty 7.0 of 10

    For any adjoint reductive group at rational Kac-Moody level, cuspidal twisted D-modules with nilpotent singular support have at least one nonzero quantum Whittaker coefficient, proved microlocally.

  5. An axiomatic approach to analytic $1$-affineness

    math.AG 2025-09 conditional novelty 6.0 of 10

    An axiomatic framework proves 1-affineness for analytic Betti stacks, analytic de Rham stacks, and rigid analytic varieties, giving categorical Künneth formulas.

  6. Quantum Entanglement, Stratified Spaces, and Topological Matter: Towards Entanglement-Sensitive Langlands Data

    quant-ph 2026-01 conditional novelty 5.0 of 10

    Witness-filtered Berry curvature, quantum geometric tensor, and quantum Fisher information obey exact lattice identities in the spinless Haldane model, with gap-crossing jumps glossed as Hecke modifications under a La...
