Basin of Attraction through Invariant Curves and Dominant Functions
We study a second-order difference equation of the form ₙ₊₁= ₙ(ₙ₋₁) + ℎ, where both () and () are decreasing. We consider a set of invariant curves at ℎ = 1 and use it to characterize the behaviour of solutions when ℎ > 1 and when 0 < ℎ < 1.The case ℎ > 1 is related to the Y2K problem. F...

| Summary: | We study a second-order difference equation of the form ₙ₊₁= ₙ(ₙ₋₁) + ℎ, where both () and () are decreasing. We consider a set of invariant curves at ℎ = 1 and use it to characterize the behaviour of solutions when ℎ > 1 and when 0 < ℎ < 1.The case ℎ > 1 is related to the Y2K problem. For 0 < ℎ < 1, we study the stability of the equilibrium solutions and find an invariant region where solutions are attracted to the stable equilibrium. In particular, for certain range of the parameters, a subset of the basin of attraction of the stable equilibrium is achieved by bounding positive solutions using the iteration of dominant functions with attracting equilibria. |
