dc.description.abstractIN THIS WORK WE PRESENT A GENERALIZED BRANS-DICKE LAGRANGIAN INCLUDING A NON-MINIMALLY COUPLED GAUSS-BONNET TERM WITHOUT IMPOSING THE VANISHING TORSION CONDITION. IN THE FIELD EQUATIONS OBTAINED THE TORSION IS CLOSED RELATED TO THE DYNAMICS OF THE SCALAR FIELD, I.E. IF NON-MINIMALLY COUPLED TERMS ARE PRESENT IN THE THEORY, THE TORSION MUST BE PRESENT. FOR THE STUDIED LAGRANGIAN WE ANALYSE THE COSMOLOGICAL CONSEQUENCES OF CONSIDER AN EFFECTIVE TORSIONAL FLUID IN THE DESCRIPTION OF THE UNIVERSE. WE SHOW THAT IN THE PROPOSED SCENARIO THE EFFECTIVE TORSIONAL FLUID CAN BE RESPONSIBLE FOR THE CURRENT ACCELERATION OF THE UNIVERSE.
