The parameter p was set to be (a) 0, (b) 1 / 8, (c) 1 / 4, (d) 3 / 8, (e) 1 / … 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} .

"WitrynaThis bifurcation is called a saddle-node bifurcation. In it, a pair of hyperbolic equilibria, one stable and one unstable, coalesce at the bifurcation point, annihilate each other and disappear.1 We refer to this bifurcation as a subcritical saddle-node bifurcation, since the equilibria exist for values of below the bifurcation value 0.
