WebDec 28, 2024 · 1 For nonlinear systems, I know the phase portrait at a fixed point is a spiral when the eigenvalues are complex conjugates with real parts, and centre when they have no real parts. But how should I determine if it's "left-handed" or "right-handed" spiral, or which way the centre is turning? ordinary-differential-equations nonlinear-system Share WebDec 15, 2024 · Fixed point method allows us to solve non linear equations. We build an iterative method, using a sequence wich converges to a fixed point of g, this fixed point is the exact solution of f (x)=0. The aim of this method is to solve equations of type: f ( x) = 0 ( E) Let x ∗ be the solution of (E). The idea is to bring back to equation of type:
