The result is a set of eigenvalues, of which the maximum real part of the complex eigenvalues is extracted as the determining stability criterion.

http://web.mit.edu/16.90/BackUp/www/pdfs/Chapter7.pdf WebOne manner that we can determine whether the integrator is stable is by plotting the eigenvalues scaled by the timestep in the complex λ∆t plane and overlaying the stability region for the desired ODE integrator. Then, ∆t can be adjusted to attempt to bring all eigenvalues into the stability region for the desired ODE integrator. Example 1.

WebMost probably we would need to check eigenvalues real part to determine stability. However $\lambda_1=0, \lambda_2=-1, \lambda_3=-2$, which makes the whole process a little more difficult, especially when it comes to check the former type of stability (eigenvalues are nonpositive and that implies solutions are Lyapunov stable).

WebNov 17, 2024 · The idea of fixed points and stability can be extended to higher-order systems of odes. Here, we consider a two-dimensional system and will need to make use of the two-dimensional Taylor series expansion of a function F(x, y) about the origin.
