The formulation of Brans-Dicke (BD) gravity with matter in the Einstein frame is realized as Einstein gravity with dilaton and dilaton coupled matter. We calculate the one-loop 4d anomaly–induced effective action (EA) due to N dilaton coupled massless fermions on the time dependent conformally flat background with non-trivial dilaton. Using such (complete) effective action, the (fourth-order) quantum–corrected equations of motion are derived. One special solution of these equations representing… CONTINUE READING
