摘要

For the quadratic Poincar'e gauge theory of gravity (PG) we consider the FLRW cosmologies using an isotropic Bianchi representation. Here the considered cosmologies are for the general case: All the even and odd parity terms of the quadratic PG with their respective scalar and pseudoscalar parameters are allowed with no a priori restrictions on their values.With the aid of a manifestly homogeneous and isotropic representation, an effective Lagrangian gives the second order dynamical equations for the gauge potentials. An equivalent set of first order equations for the observables is presented. Th generic behavior of physical solutions is discussed and illustrated using numerical simulations.
