Phrase: Cartan geometry | Statement: [Lie pseudogroup, relatedTo, Cartan geometry]

Target entity: Cartan geometry
Context triple: [Lie pseudogroup, relatedTo, Cartan geometry]

• A. Cartan connections chosen
  Cartan connections are a geometric framework generalizing affine and Riemannian connections that model curved spaces on homogeneous spaces, developed by Élie Cartan.
• B. Cartan structure equations
  Cartan structure equations are fundamental differential geometric relations that express curvature and torsion in terms of connection 1-forms on a manifold.
• C. theory of G-structures
  The theory of G-structures is a framework in differential geometry that studies geometric structures on manifolds defined by reductions of the frame bundle to a Lie group G, encompassing and unifying many classical geometries such as Riemannian, symplectic, and complex structures.
• D. Maurer–Cartan form
  The Maurer–Cartan form is a canonical Lie algebra-valued 1-form on a Lie group that encodes its infinitesimal structure and underlies many constructions in differential geometry and gauge theory.
• E. Weyl geometry
  Weyl geometry is a generalization of Riemannian geometry that allows the length of vectors to vary under parallel transport, forming the geometric framework for Weyl’s original gauge theory.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
