i need show that at the following system the zero solution is nominally stable, using some change of variable that transforme in a linear system
[tex] \frac{dx}{dt}=-x + \beta (x^2+ y^2) [/tex]
[tex] \frac{dy}{dt}=-2y + \gamma x y [/tex]
i tried with the eigenvalues of the Jacobian matrix at (0,0), but one of them is positive , then the system is unstable...
