Generalized Givental's Theorem and classification of Fano threefolds

We present Golyshev's modularity conjecture that states that the counting equations for Fano threefolds with Picard group Z (which codes their Gromov-Witten invariants) are modular. To check it we find Gromov-Witten infariants of them. For this we generalise Givental's Theorem (in the Fano case) that gives us Gromov-Witten invariants for complete intersections in toric varieties with non-negative canonical bundle.
