Description

We analytically study stabilizing solutions to Hamilton-Jacobi equations when all directions near equilibria are unstable, that is, the eigenvalues of the Jacobian matrix at the equilibria are all positive. Applying a perturbation approach, we obtain analytical approximations of stable manifolds in the corresponding Hamiltonian systems, and use their relation to the stabilizing solutions. An illustrative example is given for the two-dimensional Lotka-Volterra system and the theoretical result for the stable manifold is compared with a numerical computation to demonstrate the validity of our method.
