Bifurcations in a second-order difference equation from macroeconomics†Supported by NSFC, TRAPOYT and MOE Research grants.

Journal of Difference Equations and Applications, 2008
In this paper we discuss a second-order difference equation which was modeled from macroeconomics. Continuing Sedaghat's results on permanence, boundedness, oscillation and asymptotic stability, we discuss its flip bifurcation and Neimark–Sacker bifurcation by investigating its equivalent planar mapping and calculating its center manifold and normal ...
