Open descendant integrals in all genera

Résumé : We define graded Riemann surfaces with boundary and their moduli. We then discuss orientability of the moduli and define descendents invariants. The construction is part of a joint work with J. Solomon, extending a work with R. Pandharipande and Solomon for genus 0.
