摘要：

The effective action of a stringlike theory is considered in the cosmological context. We discuss a nonminimally coupled cosmological model and we find the existence of a Noether symmetry in the pointlike Friedman-Robertson-Walker (FRW) Lagrangian describing the model: this allows one to get interesting cosmological solutions.
