摘要：
Singularity free cosmologies, depending on the form of gravitational coupling and interaction potential, axe derived in the framework of (n + 1)-dimensional scalar-tensor theories of gravity. The results are matched with cosmological observations giving rise to realistic scenarios where the observed acceleration of cosmic fluid is recovered. Furthermore, being the solutions singularity free, the approach could work also at early epochs showing a general validity of the model.
