evaluating locally linear systems (stability, type, phase portrait)

Beschreibung

We want to solve x' = Ax. If detA =/= 0, then the origin is the only critical point. The following are different classifications of the zero vector for type and stability with corresponding phase portraits.

r1 < 0 < r2 (real and distinct eigenvalues r1, r2)
0 < r1 < r2 (real and distinct eigenvalues r1, r2) nodal source
r1 < r2 < 0 (real and distinct eigenvalues r1, r2) nodal sink
λ = 0 (r1,r2 are complex conjugates r1 = λ + iμ)
λ > 0 (r1,r2 are complex conjugates r1 = λ + iμ) spiral source
λ < 0 (r1,r2 are complex conjugates r1 = λ + iμ) spiral sink
r > 0 (r1 = r2, 1 linearly independent eigenvector) (source)
r < 0 (r1 = r2, 1 linearly independent eigenvector) (sink)
r > 0 (r1 = r2, 2 linearly independent eigenvectors) star node (source) unstable
r < 0 (r1 = r2, 2 linearly independent eigenvectors) star node (sink) asymptotically stable
