Stability of solutions to contact Hamilton-Jacobi equation on the circle
Stability of solutions to contact Hamilton-Jacobi equation on the circle
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 viscosity solutions for evolutionary contact Hamilton-Jacobi equation in the first part. In the second part, we study the existence and multiplicity of time-periodic solutions.
