Frobenius manifolds,quantum cohomology,variations of Hodge structure, TERP and tt* structures, pluriharmonic maps, DPW theory, etc |
Expository lectures on pluriharmonic maps, meromorphic connections, and quantum cohomology, followed by workshop lectures |
Despite their very different origins, the theories of (1) Gauss maps of CMC immersions (more generally, harmonic or pluriharmonic maps into symmetric spaces) (2) quantum cohomology (more generally, Frobenius manifolds) are very closely linked by means of certain families of flat connections. These "integrable systems" provide links between several important fields: differential geometry, singularity theory, variations of Hodge structures, Gromov-Witten invariants, and so on. The aim of this workshop is to exchange ideas and techniques from these fields, focusing on the meromorphic connections which arise from harmonic maps and quantum cohomology. With this in mind, three series of expository lectures are planned at the beginning of the workshop.
