论文摘要
在本文中，我们研究了一般相对性的框架中各向同性和均质宇宙的重力男性生成。我们研究了FRW指标的爱因斯坦田间方程的精确解决方案。我们的解决方案代表了宇宙的过渡模型，该模型正在减速模式下扩展，并且在宇宙常数$λ$的优势之后，它以加速模式过渡。我们观察到重力男性生成发生在衍生的宇宙中，而得出的baryon熵比与其观察值非常吻合。
In this paper, we have studied the gravitational baryogenesis of isotropic and homogeneous universe in the frame-work of general relativity. We investigate an exact and new solution of Einstein's field equations for FRW metric. Our solution represents a transitioning model of the universe which was expanding in decelerated mode and it transit in accelerated mode after dominance of cosmological constant $Λ$. We observe that gravitational baryogenesis occurs in the derived universe and derived baryon entropy ratio is in good agreement with its observational value.
