Linearization of the Hamilton–Jacobi equation

Journal of Mathematical Physics, 1986
Through a canonoid transformation the integration for the Hamilton–Jacobi equations is transformed into a two step procedure: the first being a linear problem and the second a quasilinear one. Examples are given.

The Hamilton—Jacobi Equation

2001
We already know that canonical transformations are useful for solving mechanical problems. We now want to look for a canonical transformation that transforms the 2N coordinates (q i , p i ) to 2N constant values (Q i , P i ), e.g., to the 2N initial values \((q_{i}^{0},p_{i}^{0})\) at time t = 0.

Lagrangian submanifolds and the Hamilton–Jacobi equation [PDF]

open access: yesMonatshefte Fur Mathematik, 2013
The authors present a generalized version of the geometric Hamilton-Jacobi theory in terms of certain Lagrangian submanifolds of a symplectic manifold. This allows them to give a unified presentation of Hamilton-Jacobi equations for systems with both holonomic and linear nonholonomic constraints. The formulation treats both the time-independent and the

Hamilton–Jacobi–Bellman Equations

2017
In this chapter we present recent developments in the theory of Hamilton–Jacobi–Bellman (HJB) equations as well as applications. The intention of this chapter is to exhibit novel methods and techniques introduced few years ago in order to solve long-standing questions in nonlinear optimal control theory of Ordinary Differential Equations (ODEs).

The Hamilton–Jacobi equation

2020
Abstract This chapter discusses the motion of particles which are scattered by and fall towards the center of the dipol, the motion of a particle in the Coulomb and the constant electric fields, and a particle inside a smooth elastic ellipsoid.

Solution of Hamilton Jacobi Bellman equations

Proceedings of the 39th IEEE Conference on Decision and Control (Cat. No.00CH37187), 2002
We present a method for the numerical solution of the Hamilton Jacobi Bellman PDE that arises in an infinite time optimal control problem. The method can be of higher order to reduce "the curse of dimensionality". It proceeds in two stages. First the HJB PDE is solved in a neighborhood of the origin using the power series method of Al'brecht (1961 ...

Homogenization of Metric Hamilton–Jacobi Equations

Multiscale Modeling & Simulation, 2009
In this work we provide a novel approach to homogenization for a class of static Hamilton–Jacobi (HJ) equations, which we call metric HJ equations. We relate the solutions of the HJ equations to the distance function in a corresponding Riemannian or Finslerian metric.
