标题： Generalized Cosmic Chaplygin Gas Model with or without Interaction

摘要： 最近开发的广义宇宙 Chaplygin 气体（GCCG）被研究作为暗物质和暗能量的统一模型。 为了解释最近的加速阶段，假设宇宙由辐射和 GCCG 组成。 考虑了无相互作用或有相互作用的混合情况。 对于参数的各种选择以及状态因子参数平面上的轨迹，得到了解并以图形形式展示。 对于相互作用参数的特定选择，我们展示了状态因子参数在宇宙演化不同情况中的作用。 显示英文摘要

摘要： Recently developed Generalized Cosmic Chaplygin gas (GCCG) is studied as an unified model of dark matter and dark energy. To explain the recent accelerating phase, the Universe is assumed to have a mixture of radiation and GCCG. The mixture is considered for without or with interaction. Solutions are obtained for various choices of the parameters and trajectories in the plane of the statefinder parameters and presented graphically. For particular choice of interaction parameter, we have shown the role of statefinder parameters in various cases for the evolution of the Universe.
