Resumen de Gromov�Witten invariants and moduli spaces of curves
The purpose of this note is to explain how much information of Gromov�Witten invariants of compact symplectic manifolds are determined by the geometry of moduli spaces of curves. In the case when a manifold has semisimple quantum cohomology, we believe that the information obtained this way might determine all higher genus Gromov�Witten invariants and could be used to study the Virasoro conjecture of Eguchi�Hori�Xiong and S. Katz.
