摘要：

We study the cosmological effect of the simple scalar-torsion (0(+)) mode in the Poincare gauge theory of gravity. We find that for the nonconstant (affine) curvature case the early evolution of the torsion density rho(T) has a radiation-like asymptotic behavior of a(-4) with a representing the scale factor, along with the stable point of the torsion pressure (P-T) and density ratio P-T/rho(T) -> 1/3 in the high redshift regime (z >> 0), which is different from the previous result in the literature. We use the Laurent expansion to resolve the solution. We also illustrate our result by the execution of numerical computations. DOI: 10.1103/PhysRevD.87.027301
