    Hamilton's equations give the time evolution of coordinates and conjugate momenta in four first-order differential equations, ˙ = ˙ = ⁡ ˙ = ⁡ ⁡ ⁡ ˙ = Momentum ⁠ ⁠, which corresponds to the vertical component of angular momentum ⁠ = ⁡ ⁡ ˙ ⁠, is a constant of motion. That is a consequence of the rotational symmetry of the ...

  3. Hamilton–Jacobi equation - Wikipedia

    en.wikipedia.org/wiki/Hamilton–Jacobi_equation

    In physics, the Hamilton–Jacobi equation, named after William Rowan Hamilton and Carl Gustav Jacob Jacobi, is an alternative formulation of classical mechanics, equivalent to other formulations such as Newton's laws of motion, Lagrangian mechanics and Hamiltonian mechanics.

  4. Hamilton–Jacobi–Bellman equation - Wikipedia

    en.wikipedia.org/wiki/Hamilton–Jacobi–Bellman...

    The equation is a result of the theory of dynamic programming which was pioneered in the 1950s by Richard Bellman and coworkers. [4] [5] [6] The connection to the Hamilton–Jacobi equation from classical physics was first drawn by Rudolf Kálmán. [7] In discrete-time problems, the analogous difference equation is usually referred to as the ...

  5. Hamiltonian system - Wikipedia

    en.wikipedia.org/wiki/Hamiltonian_system

    A Hamiltonian system is a dynamical system governed by Hamilton's equations. In physics, this dynamical system describes the evolution of a physical system such as a planetary system or an electron in an electromagnetic field. These systems can be studied in both Hamiltonian mechanics and dynamical systems theory.

  7. Symplectic integrator - Wikipedia

    en.wikipedia.org/wiki/Symplectic_integrator

    The time evolution of Hamilton's equations is a symplectomorphism, meaning that it conserves the symplectic 2-form. A numerical scheme is a symplectic integrator if it also conserves this 2-form. A numerical scheme is a symplectic integrator if it also conserves this 2-form.

  8. Viscosity solution - Wikipedia

    en.wikipedia.org/wiki/Viscosity_solution

    It has been found that the viscosity solution is the natural solution concept to use in many applications of PDE's, including for example first order equations arising in dynamic programming (the Hamilton–Jacobi–Bellman equation), differential games (the Hamilton–Jacobi–Isaacs equation) or front evolution problems, [1] [2] as well as ...

  9. Hamiltonian (quantum mechanics) - Wikipedia

    en.wikipedia.org/wiki/Hamiltonian_(quantum...

    This equation is the Schrödinger equation. It takes the same form as the Hamilton–Jacobi equation , which is one of the reasons H {\displaystyle H} is also called the Hamiltonian. Given the state at some initial time ( t = 0 {\displaystyle t=0} ), we can solve it to obtain the state at any subsequent time.
