Resumen
We show that the already known Bianchi type-I cosmological solutions of the self-consistent Einstein-Cartan theory contain computational errors that lead to an incomplete analysis of the appearance of inflation in the models. Other possibilities for a phase of accelerated expansion driven by spin effects are presented. © 1990. 145 2-3 74 78 Bradas, Fennelly, Smalley, (1987) Phys. Rev.
