### Abstract

We investigate the asymptotic behavior of solutions of Hamilton-Jacobi equations with large Hamiltonian drift terms in an open subset of the two-dimensional Euclidean space. The drift is given by ϵ - 1 ( H x 2 , - H x 1 ) ^{-1}(H_{2},-H_{x}1) of a Hamiltonian H, with ϵ > 0 >0 . We establish the convergence, as ϵ → 0 + to 0+ , of solutions of the Hamilton-Jacobi equations and identify the limit of the solutions as the solution of systems of ordinary differential equations on a graph. This result generalizes the previous one obtained by the author to the case where the Hamiltonian H admits a degenerate critical point and, as a consequence, the graph may have more than four segments at a node.
