Abstract: In this paper, we investigate the bifurcations of a multiplier-accelerator model with nonlinear investment function in an anticyclical fiscal policy rule. First, we give the conditions that the model produces supercritical ...

Abstract: In this paper, we investigate the traveling wave solutions of a two-component Dullin–Gottwald–Holm (DGH) system. By qualitative analysis methods of planar systems, we investigate completely the topological behavior of the ...
