Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Maurer–Cartan equation | Statement: [Maurer–Cartan form, satisfies, Maurer–Cartan equation]

Target entity: Maurer–Cartan equation
Context triple: [Maurer–Cartan form, satisfies, Maurer–Cartan equation]

• A. 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.
• 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. Cartan connections
  Cartan connections are a geometric framework generalizing affine and Riemannian connections that model curved spaces on homogeneous spaces, developed by Élie Cartan.
• D. Cartan magic formula
  The Cartan magic formula is a fundamental identity in differential geometry that expresses the Lie derivative of a differential form in terms of the exterior derivative and interior product.
• E. Cartan formula
  The Cartan formula is a fundamental identity in differential geometry that expresses the Lie derivative of a differential form in terms of the exterior derivative and interior product.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
