Object Hodge star operator
The Hodge star operator is a linear map on differential forms in oriented Riemannian manifolds that sends a k-form to an (n−k)-form in a way that encodes the metric and orientation, enabling duality operations such as defining codifferentials and expressing vector calculus identities.

NER Named-entity recognition gpt-5-mini
Instruction
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).
Input
Phrase: Hodge star operator | Statement: [Levi-Civita symbol, relatedConcept, Hodge star operator]

Target entity: Hodge star operator
Context triple: [Levi-Civita symbol, relatedConcept, Hodge star operator]
  • A. Hodge Laplacian
    The Hodge Laplacian is a differential operator on differential forms of a Riemannian manifold that combines the exterior derivative and its adjoint to study harmonic forms and de Rham cohomology.
  • B. Lefschetz operator
    The Lefschetz operator is a linear operator in Kähler geometry that acts on differential forms by wedging with the Kähler form, playing a central role in the Hard Lefschetz theorem and Hodge theory.
  • C. Fubini–Study form
    The Fubini–Study form is the canonical Kähler form on complex projective space, encoding its standard Hermitian and symplectic geometry.
  • D. Hodge decomposition
    Hodge decomposition is a fundamental result in differential geometry and Hodge theory that expresses differential forms on a Riemannian manifold uniquely as sums of exact, co-exact, and harmonic components.
  • E. Dirac operator
    The Dirac operator is a fundamental first-order differential operator on spinor fields that generalizes the classical Dirac equation and plays a central role in geometry, topology, and quantum field theory.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
