WebThe fixed point is an unstable improper node. This is shown in the second snapshot. For , the eigenvalues are real, positive, and distinct; in these circumstances, all trajectories are tangential to the eigenvector associated with the smaller eigenvalue (except those directly along the other eigenvector), and the fixed point is an unstable node. WebAsymptotic stability of fixed points of a non-linear system can often be established using the Hartman–Grobman theorem. Suppose that v is a C 1-vector field in R n which vanishes at a point p, v(p) = 0. Then the corresponding autonomous system ′ = has a constant solution =.
