The 32 pages that link to Gauge symmetry, each with the reason it gives.

• Lagrangian mechanicsRelated: Gauge freedom can appear as non-uniqueness in Lagrangians describing the same dynamics.

• Gauge theoryRelated: Its local form is the organizing principle behind gauge theories.

• Noether's theoremRelated: Its arbitrary-function parameters place it in the domain of Noether's second theorem.

• Spontaneous symmetry breakingCompared with: Gauge symmetry is a descriptive redundancy, so its apparent breaking differs from breaking a physical global symmetry.

• SymmetryRelated: Physical symmetry can concern equivalent descriptions, not only visible shapes.

• Color chargeNarrower topic: Local gauge symmetry gives color charge its role in QCD.

• Invariant (mathematics)Related: It distinguishes changes in description from changes in invariant physical content.

• Charge conjugationRelated: Charge conjugation acts on gauge fields as well as charged matter fields.

• Higgs fieldRelated: The Higgs field’s interactions let the Standard Model retain gauge symmetry while its vacuum hides part of it.

• Gauge bosonNarrower topic: Gauge bosons arise when local symmetries are built into a physical theory.

• Symmetry groupRelated: Gauge transformations form symmetry structures central to modern field theories.

• Yang–Mills theoryRelated: Local gauge symmetry constrains the fields and interactions in Yang–Mills theory.

• Electromagnetic interactionRelated: Local gauge symmetry underlies the standard formulation of electromagnetic theory.

• Quotient spaceRelated: Identifying redundant configurations is a quotient construction in many gauge theories.

• Charge conservationNarrower topic: Electromagnetic gauge symmetry underlies the field-theoretic account of conserved electric charge.

• Classical electromagnetismRelated: Electromagnetic potentials can change under gauge transformations without changing the fields.

• Gauge fixingNarrower topic: Gauge fixing chooses one description from the equivalence generated by this symmetry.

• Ginzburg–Landau theoryRelated: Electromagnetic gauge coupling makes the theory respond consistently to vector potentials.

• Symmetry in physicsBroader topic: Local symmetries shape the interactions and constraints of gauge theories.

• Fundamental interactionRelated: Gauge symmetries structure the Standard Model's descriptions of three interactions.

• Uniqueness of solutionsRelated: Gauge-related mathematical descriptions can represent the same physical state, complicating literal uniqueness.

• Electroweak epochNarrower topic: The epoch's defining unity was a gauge symmetry of the electroweak theory.

• General covarianceRelated: It clarifies why coordinate freedom need not be a physical symmetry between distinct states.

• Weak isospinNarrower topic: Weak isospin arises from a local SU(2) gauge symmetry.

• Noether's second theoremRelated: Gauge transformations are the standard source of arbitrary-function symmetries covered by the theorem.

• Ward–Takahashi identityRelated: Gauge invariance is the principal symmetry whose quantum consequences the identity captures.

• Weak hyperchargeNarrower topic: The quantum number is defined by a representation of an electroweak gauge symmetry.

• Faddeev–Popov ghostNarrower topic: Ghosts arise because this redundancy makes the unfixed path integral overcount configurations.

• Symmetry in quantum mechanicsRelated: It differs from ordinary global symmetry because gauge-related descriptions represent the same physical state.

• Hypothetical particle physics modelsRelated: Proposed forces often arise by enlarging the Standard Model's gauge symmetries.

• Methods in electromagnetismRelated: It explains why potential-based formulations can have multiple equivalent descriptions.

• Symmetry-based models (mathematical physics)Broader topic: Local gauge invariance constrains interactions and underlies many modern field theories.
