Phrase: Cauchy problem | Statement: [Lax equivalence theorem, relatedTo, Cauchy problem]

Target entity: Cauchy problem
Context triple: [Lax equivalence theorem, relatedTo, Cauchy problem]

• A. Cauchy problem chosen
  The Cauchy problem is a fundamental type of initial value problem in partial differential equations, where one seeks a solution satisfying prescribed data on a given initial surface.
• B. Cauchy–Kovalevskaya theorem
  The Cauchy–Kovalevskaya theorem is a fundamental result in partial differential equations that guarantees the existence and uniqueness of analytic solutions to certain initial value problems under appropriate analyticity conditions.
• C. Lectures on Cauchy’s problem in linear partial differential equations
  "Lectures on Cauchy’s Problem in Linear Partial Differential Equations" is a classic mathematical treatise by Jacques Hadamard that systematically develops the theory of existence, uniqueness, and well-posedness for solutions to linear partial differential equations.
• D. d’Alembert’s formula
  d’Alembert’s formula is a classical solution method for the one-dimensional wave equation that expresses the displacement of a vibrating string in terms of its initial shape and velocity.
• E. Cauchy–Euler equation
  The Cauchy–Euler equation is a type of linear ordinary differential equation with variable coefficients that often appears in problems with power-law or scale-invariant behavior.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
