Hamilton-Jacobi equation [′ham·əl·tən jə′kō·bē i‚kwā·zhən]
(mathematics) A particular partial differential equation useful in studying certain systems of ordinary equations arising in the calculus of variations, dynamics, and optics:H(q1, …,qn, ∂φ/∂q1, …, ∂φ/∂qn,t) + ∂φ/∂t= 0, whereq1, …,qnare generalized coordinates,tis the time coordinate,His the Hamiltonian function, and φ is a function that generates a transformation by means of which the generalized coordinates and momenta may be expressed in terms of new generalized coordinates and momenta which are constants of motion.
