Input
Phrase: Korteweg–de Vries equation | Statement: [Robert Miura, studies, Korteweg–de Vries equation]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07 
Target entity: Korteweg–de Vries equation
Context triple: [Robert Miura, studies, Korteweg–de Vries equation]
  • A. Korteweg–De Vries equation chosen
    The Korteweg–De Vries equation is a fundamental nonlinear partial differential equation that models shallow water waves and solitons, playing a central role in the theory of integrable systems.
  • B. Kadomtsev–Petviashvili equation
    The Kadomtsev–Petviashvili equation is a fundamental nonlinear partial differential equation in mathematical physics that generalizes the Korteweg–De Vries equation to two spatial dimensions to describe the evolution of weakly dispersive, weakly nonlinear waves.
  • C. Zur Theorie der nichtlinearen Wellen
    "Zur Theorie der nichtlinearen Wellen" is Klaus Hasselmann's doctoral thesis, a foundational work on the behavior and mathematical description of nonlinear waves in physics.
  • D. Painlevé–Kruskal theorem
    The Painlevé–Kruskal theorem is a result in the theory of nonlinear differential equations that characterizes integrability through the analytic structure of their solutions, particularly via the Painlevé property.
  • E. Liouville equation
    The Liouville equation is a fundamental differential equation in statistical mechanics and Hamiltonian dynamics that governs the time evolution of a system’s phase-space probability density.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
