| Abstract: |
| In this paper,the dynamical analysis is performed for a spatially flat universe governed by a special model of f(R,T) gravity.The critical points are classified and a three-dimensional attractor is found.Especially,in the case of T=0,the phase portrait is plotted for the two-dimensional autonomous system. |
| Key words: modified gravity theory attractor the phase portrait |
