WitrynaIn addition, this equation is a typical amplitude equation for imperfect steady bifurcations with cubic nonlinearities. Whenδ=0, we have found thatλ=0 is not the point where the bifurcation transition is observed. This transition appears at a valueλ =λ j > 0. We call λj the delay of the bifurcation transition. WitrynaThe word bifurcatemeans “to divide into two parts or branches.” Hence, a bifurcation diagram shows us at what parameter values additional solutions emerge (or disappear). The bifurcation diagram is constructed by plotting the parameter value kagainst all corresponding equilibrium values \( y^{\ast} .
