| Towards Open String Mirror Symmetry for One-Parameter Calabi-Yau Hypersurfaces I |
| Speaker: | Johanna Knapp (Max-Planck-Institut für Physik (Werner-Heisenberg-Institut), München ) |
| Abstract: | This talk is concerned with branes and differential equations for one-parameter Calabi-Yau hypersurfaces in weighted projective spaces. For a certain class of B-branes we derive the inhomogeneous Picard-Fuchs equations satisfied by the brane superpotential. One central ingredient is the representation of these branes by matrix factorizations. Using the physical realization of the equivalence of categories of matrix factorizations and coherent sheaves, we relate them to geometry. In this way we arrive at Griffiths' normal function for the branes and the prediction for the real BPS invariants for holomorphic maps of worldsheets with low Euler characteristics, ending on the mirror A-branes |
