Dirac equation

Target entity: Dirac equation
Context triple: [Feynman checkerboard model, relatedTo, Dirac equation]

• A. Maxwell's equations
  Maxwell's equations are the fundamental set of four equations in classical electromagnetism that describe how electric and magnetic fields are generated and interact with charges and currents.
• B. Dyson’s proof of equivalence of Feynman and Schwinger–Tomonaga formulations of QED
  Dyson’s proof of equivalence of Feynman and Schwinger–Tomonaga formulations of QED is a landmark theoretical result that rigorously demonstrated the mathematical consistency and mutual compatibility of different approaches to quantum electrodynamics.
• C. Einstein field equations
  The Einstein field equations are the core mathematical framework of general relativity, relating the curvature of spacetime to the distribution of matter and energy.
• D. Feynman–Hellmann theorem
  The Feynman–Hellmann theorem is a result in quantum mechanics that relates the derivative of an energy eigenvalue with respect to a parameter in the Hamiltonian to the expectation value of the corresponding derivative of the Hamiltonian.
• E. Fokker–Planck equation
  The Fokker–Planck equation is a partial differential equation that describes the time evolution of the probability density function of a stochastic (random) process, such as Brownian motion.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
