Abstract
We consider the Noether Symmetry Approach for a cosmological model derived from a tachyon scalar field T with a Dirac-Born-Infeld Lagrangian and a potential V(T). Furthermore, we assume a coupled canonical scalar field Φ with an arbitrary interaction potential B(T, Φ). Exact solutions are derived consistent with the accelerated behavior of cosmic fluid.File in questo prodotto:
