Abstract: In the first part of this talk, we discuss geometrical interpretation of the B-model data for the mirror computation of closed Gromov-Witten invariants of projective hypersurfaces. We reconstruct these data as intersection numbers of the moduli space of polynomial maps. In the second part, we apply the result of the first part to evaluation of open Gromov-Witten invariants of projective hypersurfaces. Our construction provides an extension of Walcher's result of disk invariants of quintic 3-fold to higher dimensional Calabi-Yau hypersurfaces in CP^{N-1}.
