| Abstract: | In the current picture mirror symmetry for Calabi-Yau 3 folds is linked up with points in the moduli space of maximal degeneration. However, recently examples of Calabi-Yau threefolds without such points were described by B. van Geemen, A. Garbagnati and J. Rohde. I will report on recent joint work with S. Cynk on the computation of conifold periods, which led to the discovery of new examples, whose Picard-Fuchs equation has Sp_4 as differential Galois group. |
