On the inhomogeneous discounted Hamilton-Jacobi equations

Liang Jin, Jun Yan, Kai Zhao

In this paper, we study the family of inhomogeneous discounted Hamilton-Jacobi equations \begin{equation}\label{hjs1} λ(x)u+h(x,d_x u)=c \quad \tag{} \end{equation} on a clos…

On the dynamics of contact Hamiltonian systems II: Variational construction of asymptotic orbits

Liang Jin, Jun Yan, Kai Zhao

This paper is a continuation of our study of the dynamics of contact Hamiltonian systems in \cite{JY}, but without monotonicity assumption. Due to the complexity of general cases,…

Dynamics of globally minimizing orbits in contact Hamiltonian systems

Yang Xu, Jun Yan, Kai Zhao

In this paper, we study the asymptotic behavior of globally minimizing orbits of contact Hamiltonian systems. Under some assumptions, we prove that the -limit set of globally mi…

Stability of solutions to contact Hamilton-Jacobi equation on the circle

Yang Xu, Jun Yan, Kai Zhao

Combing the weak KAM method for contact Hamiltonian systems and the theory of viscosity solutions for Hamilton-Jacobi equations, we study the Lyapunov stability and instability of…

Time periodic and almost periodic viscosity solutions of contact Hamilton-Jacobi equations on

Kaizhi Wang, Jun Yan, Kai Zhao

This paper concerns with the time periodic viscosity solution problem for a class of evolutionary contact Hamilton-Jacobi equations with time independent Hamiltonians on the torus…
