Poincaré’s theory of rotating fluid masses

Target entity: Poincaré’s theory of rotating fluid masses
Context triple: [Riemann ellipsoid, relatedTo, Poincaré’s theory of rotating fluid masses]

• A. Chandrasekhar’s theory of ellipsoidal figures of equilibrium
  Chandrasekhar’s theory of ellipsoidal figures of equilibrium is a foundational mathematical framework in astrophysics that analyzes the shapes, stability, and rotational properties of self-gravitating fluid masses modeled as ellipsoids.
• B. On the rotation of a solid body about a fixed point
  "On the Rotation of a Solid Body About a Fixed Point" is a landmark mathematical treatise in rigid body dynamics that contributed fundamentally to the theory of differential equations and classical mechanics.
• C. On the effect of the internal friction of fluids on the motion of pendulums
  "On the Effect of the Internal Friction of Fluids on the Motion of Pendulums" is an 1851 scientific paper by George Gabriel Stokes that laid the foundations of fluid dynamics by analyzing viscous forces and leading to what is now known as Stokes' law.
• D. Mémoire sur les lois du mouvement des fluides
  Mémoire sur les lois du mouvement des fluides is a foundational scientific treatise in which Claude-Louis Navier formulated the equations governing the motion of viscous fluids, now known as the Navier–Stokes equations.
• E. Painlevé conjecture in celestial mechanics
  The Painlevé conjecture in celestial mechanics is a hypothesis about the possible occurrence of non-collision singularities—where bodies in an N-body gravitational system exhibit infinite behavior in finite time without actually colliding.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
