Hi all,
it seems that there is a rule of thumb used by some researchers looking at nonlinear systems whereby they determine the stability of fixed points based on the product of the gradients of the null clines at the point where they intersect. in particular if the product of the gradients...
hi all,
i have a question regarding saddle points. I'm looking at a 2D system which has a trapping region, all trajectories on the boundary point in. from strogatz's book on nonlinear systems I've read about index theory and so as i understand it the index of this region is +1 and the sum of...
