具有可变号相互作用项的广义Chaplygin宇宙学

Generalized Chaplygin cosmology with changeable-signs interactions

利用相空间分析方法,讨论两种不同的可变号相互作用项的广义Chaplygin气体动力学.在这两类模型中找到了一些新的稳定吸引子解及异宿轨线解.

Using phase space analysis methods,we discuss two kinds of Generalized Chaplygin cosmology with changeable-signs interactions dynamically. Some new stable attractor solutions and heteroclinic trajectory solutions are found in these two types of models.
