We review a notion of completeness in QFT arising from the analysis of basic properties of the set of operator algebras attached to regions. In words, this completeness asserts that the physical observable algebras produced by local degrees of freedom are the maximal ones compatible with causality. We elaborate on equivalent statements to this completeness principle such as the non-existence of generalized symmetries and the uniqueness of the net of algebras. We clarify that for non-complete theories, the existence of generalized symmetries is unavoidable, and further, that they always come in dual pairs with precisely the same ``size''. Moreover, the dual symmetries are always broken together, be it explicitly or effectively. Finally, we comment on several issues raised in recent literature, such as the relationship between completeness and modular invariance, dense sets of charges, and absence of generalized symmetries in the bulk of holographic theories.

  1. Algebraic locality and non-invertible Gauss laws

    hep-th 2026-05 unverdicted novelty 7.0 of 10

    Non-invertible Gauss laws on lattices preserve Haag duality exactly only on cuspless regions; cusped regions require a collar, and group double models satisfy disjoint additivity.

  2. Disjoint additivity and local quantum physics

    hep-th 2025-09 conditional novelty 7.0 of 10

    Local quantum systems should obey disjoint additivity plus Haag duality, a combination that survives higher-form symmetries and fails for known nonlocal constructions.

  3. Symmetry, Symmetry Topological Field Theory and von Neumann Algebra

    hep-th 2025-07 conditional novelty 6.0 of 10

    The symmetric-sector von Neumann algebra of a QFT violates additivity or Haag duality exactly when the Lagrangian algebra of its SymTFT contains operators beyond the identity, with a sharper criterion distinguishing t...

  4. Selection rules for RG flows of minimal models

    hep-th 2024-12 conditional novelty 6.0 of 10

    A constructive enumeration of all local minimal-model CFTs, organized by Jones index, yields selection rules for RG flows that recover known results and predict new ones.

  5. Gauge-invariant charges of the dual graviton

    hep-th 2024-12 conditional novelty 6.0 of 10

    The dual graviton theory admits gauge-invariant Penrose-type charges that refine the Noether charges, and under duality some charges stay magnetic in both descriptions while others stay electric in both.
