+ | The idea of the calculation of the Hilbert function of the moduli spaces of vector bundles on Riemann surfaces goes back to the works of Michael Thaddeus in the early 90’s. | ||

- | The rigid Calabi-Yau threefolds that appear as conifold fibers | ||
- | in the hypergeometric Landau-Ginzburg models of Fano | ||
- | complete intersection fourfolds in [weighted] projective spaces | ||
- | are expected to be modular, but what is lacking is the | ||
- | construction of actual correspondences with Kuga-Sato | ||
- | threefolds. I will explain how the technique of fibered motives | ||
- | can be used to provide `opportunistic' | ||
- | proofs for such fibers. | ||
