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: Friedmann equations | Statement: [Alexander Friedmann, knownFor, Friedmann equations]

Target entity: Friedmann equations
Context triple: [Alexander Friedmann, knownFor, Friedmann equations]

• A. FLRW cosmological models
  FLRW cosmological models are a family of solutions to Einstein’s field equations that describe a homogeneous and isotropic expanding or contracting universe, forming the standard framework for modern cosmology.
• B. Einstein field equations
  The Einstein field equations are the core mathematical framework of general relativity, relating the curvature of spacetime to the distribution of matter and energy.
• C. Schwarzschild–Milne equations
  The Schwarzschild–Milne equations are fundamental integro-differential equations in radiative transfer theory that describe the propagation and scattering of radiation through a plane-parallel, absorbing and emitting medium.
• D. Big Bang cosmology
  Big Bang cosmology is the prevailing scientific framework that explains the origin, early evolution, and large-scale structure of the universe as emerging from an extremely hot, dense initial state that has been expanding over time.
• E. Einstein–Maxwell equations
  The Einstein–Maxwell equations are the coupled set of field equations in general relativity that describe how spacetime curvature and electromagnetic fields interact and influence each other.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Entity: Friedmann equations
Triple: [Alexander Friedmann, knownFor, Friedmann equations]

The Friedmann equations are fundamental cosmological equations in general relativity that describe how the universe’s scale factor evolves over time, relating its expansion to matter, radiation, curvature, and dark energy content.
