论文摘要
我们得出了Weyssenhoff流体的爱因斯坦 - 卡丹场方程的线性标量扰动方程，以及比安奇身份和地球方程的相应扰动。这些方程式在牛顿形和同步仪中均给出。当扭转的精确演变及其扰动将从宇宙中大规模结构的N体宇宙模拟中提取时，它们适合数值实现。一致性宇宙学模型的数量不断增加，迫使我们包括通过爱因斯坦 - 卡丹重力中扭转实现的旋转自由度。
We derive linear scalar perturbation equations for Einstein-Cartan field equations of Weyssenhoff fluid, as well as for the corresponding perturbations of Bianchi identity and geodesic equations. The equations are given in both conformal Newtonian and synchronous gauges. They are suitable for numerical implementation when precise evolution of torsion and its perturbation will be extracted from N-body cosmic simulations of the large scale structures in the Universe. A rising number of problems of the concordance cosmological model forces us to include the rotational degrees of freedom realized through torsion in the Einstein-Cartan gravity.
