WebApr 9, 2024 · A saddle-node bifurcation is a local bifurcation in which two (or more) critical points (or equilibria) of a differential equation (or a dynamic system) collide and annihilate each other. Saddle-node bifurcations may be associated with hysteresis and catastrophes. Consider the slope function \( f(x, \alpha ) , \) where α is a control parameter. In this … WebWhen it is applied to determine a fixed point in the equation x = g(x), it consists in the following stages: select x0; calculate x1 = g(x0), x2 = g(x1); calculate x3 = x2 + γ2 1 − γ2(x2 − x1), where γ2 = x2 − x1 x1 − x0; calculate x4 = g(x3), x5 = g(x4); calculate x6 as the extrapolate of {x3, x4, x5}. Continue this procedure, ad infinatum.
