随机爱因斯坦方程

Stochastic Einstein equations

Vladimir Dzhunushaliev

摘要:

考虑了三维空间度规$γ_{ij}$为随机函数时的随机爱因斯坦方程。随机量的概率密度与Perelman熵泛函有关。以弗里德曼宇宙为例。结果表明,弗里德曼宇宙的动力学演化是不变的。讨论了广义相对论与Ricci流之间的联系。

英文摘要:

Stochastic Einstein equations are considered when 3D space metric $γ_{ij}$ are stochastic functions. The probability density for the stochastic quantities is connected with the Perelman's entropy functional. As an example, the Friedman Universe is considered. It is shown that for the Friedman Universe the dynamical evolution is not changed. The connection between general relativity and Ricci flows is discussed.
