Abstract
We explore the recently introduced modified Gauss-Bonnet gravity [1], pragmatic with , the Gauss-Bonnet term, and , the trace of the energy-momentum tensor. Noether symmetry approach has been used to develop some cosmologically viable gravity models. The Noether equations of modified gravity are reported for flat FRW universe. Two specific models have been studied to determine the conserved quantities and exact solutions. In particular, the well known deSitter solution is reconstructed for some specific choice of gravity model.
