NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Ledoux criterion
Context triple: [Schwarzschild criterion, isSpecialCaseOf, Ledoux criterion]
  • A. Schwarzschild criterion
    The Schwarzschild criterion is a condition in astrophysics that determines when a star’s interior becomes convectively unstable, leading to energy transport by bulk motion of stellar material.
  • B. Courant–Friedrichs–Lewy condition
    The Courant–Friedrichs–Lewy condition is a fundamental stability criterion in numerical analysis that restricts the time step size in discretized partial differential equations to ensure convergence of the computed solution.
  • C. Ledoux
    Ledoux is a French surname most famously associated with Claude Nicolas Ledoux, an influential 18th-century neoclassical architect and urban planner.
  • D. Goodman–Martínez–Thompson correlation
    The Goodman–Martínez–Thompson correlation is the most widely accepted scholarly conversion formula that aligns dates in the ancient Maya Long Count calendar with the Gregorian calendar.
  • E. Saffman
    Saffman is a surname most notably associated with Philip G. Saffman, a prominent British-American applied mathematician and fluid dynamicist.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
