Coercive Hamilton–Jacobi equations in domains: the twin blow-ups method

open access: yesComptes Rendus. Mathématique
In this note, we consider an evolution coercive Hamilton–Jacobi equation posed in a domain and supplemented with a boundary condition. We are interested in proving a comparison principle in the case where the time and the (normal) gradient variables are ...

Bohm's potential, classical/quantum duality and repulsive gravity

open access: yesPhysics Letters B, 2019
We propose the notion of a classical/quantum duality in the gravitational case (it can be extended to other interactions). By this one means exchanging Bohm's quantum potential for the classical potential VQ↔V in the stationary quantum Hamilton–Jacobi ...

Hopf-type estimates for solutions to Hamilton-Jacobi equations with concave-convex initial data

open access: yesElectronic Journal of Differential Equations, 2003
We consider the Cauchy problem for the Hamilton-Jacobi equations with concave-convex initial data. A Hopf-type formula for global Lipschitz solutions and estimates for viscosity solutions of this problem are obtained using techniques of multifunctions ...

Massive vector particles tunneling from Kerr and Kerr–Newman black holes

open access: yesPhysics Letters B, 2015
In this paper, we investigate the Hawking radiation of massive spin-1 particles from 4-dimensional Kerr and Kerr–Newman black holes. By applying the Hamilton–Jacobi ansatz and the WKB approximation to the field equations of the massive bosons in Kerr and

Hamilton-Jacobi equation in momentum space

open access: yesOptics Express, 2006
The application of the Hamilton-Jacobi equation to isotropic optical materials leads to the well-known eikonal equation which provides the surfaces normal to the ray trajectories. The symmetry between the coordinates x=(x(1),x(2),x(3)) and the momenta p=(p(1),p(2),p(3)) in the Hamiltonian formulation of Geometrical Optics establishes a dual Hamilton ...

Dispersionless Hirota Equations of Two-Component BKP Hierarchy

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2006
The BKP hierarchy has a two-component analogue (the 2-BKP hierarchy). Dispersionless limit of this multi-component hierarchy is considered on the level of the τ-function.

On Exact Multidimensional Solutions of a Nonlinear System of First Order Partial Differential Equations

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2019
This study is concerned with a system of two nonlinear first order partial differential equations. The right-hand sides of the system contain the squares of the gradients of the unknown functions.

On the Hamilton-Jacobi-Bellman Equation by the Homotopy Perturbation Method

open access: yesAbstract and Applied Analysis, 2014
Our concern in this paper is to use the homotopy decomposition method to solve the Hamilton-Jacobi-Bellman equation (HJB). The approach is obviously extremely well organized and is an influential procedure in obtaining the solutions of the equations.

Continuous dependence estimates for viscosity solutions of fully nonlinear degenerate elliptic equations

open access: yesElectronic Journal of Differential Equations, 2002
Using the maximum principle for semicontinuous functions [3,4], we prove a general ``continuous dependence on the nonlinearities'' estimate for bounded Holder continuous viscosity solutions of fully nonlinear degenerate elliptic equations.
