f(T)引力中的广义Noether对称性

Generalized Noether symmetry in f(T) gravity

H. Mohseni Sadjadi

摘要:

我们考虑修正的遥平行引力(f(T)引力),作为一个框架来解释目前的宇宙加速膨胀。物质成分被假定为冷暗物质。为了得到函数$f$的显式形式,我们利用广义Noether定理,并使用广义向量场作为相应拉格朗日量的变分对称。我们研究所获得的结果的宇宙学后果。

英文摘要:

We consider modified teleparallel gravity, (f(T) gravity), as a framework to explain the present accelerated expansion of the universe. The matter component is assumed to be cold dark matter. To find the explicit form of the function $f$, we utilize generalized Noether theorem and use generalized vector fields as variational symmetries of the corresponding Lagrangian. We study the cosmological consequences of the obtained results.
