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: Pontryagin maximum principle | Statement: [Lev Pontryagin, notableWork, Pontryagin maximum principle]

Target entity: Pontryagin maximum principle
Context triple: [Lev Pontryagin, notableWork, Pontryagin maximum principle]

• A. Hamilton’s maximum principle
  Hamilton’s maximum principle is a fundamental analytical tool in geometric analysis that extends the classical maximum principle to tensor-valued quantities, playing a key role in studying the behavior of solutions to the Ricci flow and related geometric evolution equations.
• B. Introduction to Stochastic Control Theory
  Introduction to Stochastic Control Theory is a foundational textbook that systematically develops the theory and methods for controlling dynamical systems under uncertainty using probabilistic and stochastic-process tools.
• C. Hamilton–Jacobi equation
  The Hamilton–Jacobi equation is a fundamental partial differential equation in classical mechanics that reformulates dynamics in terms of a generating function, providing a powerful bridge to quantum mechanics and modern analytical methods.
• D. Karush–Kuhn–Tucker conditions
  The Karush–Kuhn–Tucker conditions are fundamental optimality criteria in nonlinear programming that generalize Lagrange multipliers to handle inequality constraints.
• E. Euler–Lagrange equation
  The Euler–Lagrange equation is a fundamental differential equation in the calculus of variations that provides the condition for a function to make a functional stationary, forming the basis of Lagrangian mechanics and many physical theories.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
