A new selection problem for degenerate viscous Hamilton-Jacobi equations
Qinbo Chen, Zhi-Xiang Zhu
We study a selection problem for degenerate viscous Hamilton--Jacobi equations with convex Hamiltonians, in which the approximation procedure combines a nonlinear discounted approx…

Dynamic and asymptotic behavior of singularities of certain weak KAM solutions on the torus
Piermarco Cannarsa, Qinbo Chen, Wei Cheng
For mechanical Hamiltonian systems on the torus, we study the dynamical properties of the generalized characteristics semiflows associated with certain Hamilton-Jacobi equations, a…
