Abstract:	We investigate the (small) quantum cohomology ring of the moduli spaces $overline {mathcal {M}}_{0,n}$ of stable n-pointed curves of genus 0. In particular, we determine an explicit presentation in the case n = 5 and we outline a computational approach to the case n = 6. This research was partially supported by MIUR and GNSAGA of INdAM (Italy).

Keywords:	Moduli spaces Pointed rational curves Quantum cohomology Gromov– Witten invariants
