The quantum geometry of genus one fibered Calabi-Yau threefolds

The enumerative geometry of Calabi-Yau manifolds and its interplay with string dualities, most notably mirror symmetry, is by now a classical topic. Nonetheless it continues to lead to new insights in mathematics as well as string theory. In particular, there has been a renewed interest in the properties of genus one fibered Calabi-Yaus, mainly due to their importance for F-theory and geometrical engineering of gauge theories.
I will review the basics of topological strings and topological branes and then describe recent progress in understanding and leveraging the quantum geometry of Calabi-Yau manifolds that exhibit a genus one fibration.
The results are, via dualities, related to the supersymmetry protected quantities of a variety of different physical theories. The talk is based on 1902.08215, 1910.01988, 1911.09697 and 1912.09493.
