The Oberseminar is a very long running seminar at MPI (‘Ober‘ standing for 'upper'). Its idea is that the guests of the MPI speak in this seminar (hopefully early in their stay) and get the chance to explain their work to the other guests.

Conference on "Integrability, Geometry and Moduli" July 29 - August 2, 2019

This is a conference in honor of Motohico Mulase's 65th birthday. It will cover recent advances around the following themes

Quantization of moduli spaces, in particular the Hitchin moduli space of Higgs bundles
Gromov-Witten theory, Frobenius manifolds, integrable hierarchies, cohomological field theories
Geometry of quiver varieties, wall-crossing phenomena
Mirror symmetry, topological string theory, quantum invariants of 3-manifolds
Topological recursion, quantum curves, and application to geometry and enumerative problems (Hurwitz theory, random matrix theory, ribbon graphs)

Connections between these fields are apparent from the physics perspective and research is trying to make rigorous sense of these relationships. Encouraging the exchanges between mathematicians and theoretical physicists will thus be an important dimension of the conference. More details available soon.

The study of harmonic morphisms in the 3-dimensional Euclidean space
goes back to a paper of Jacobi from 1848. This was then introduced into
the setting of Riemannian geometry, in the late 1970s by Fuglede and
Ishihara, independently. A harmonic morphism $\phi : (M, g)\to (N, h)$
between two Riemannian manifolds is a map that pulls back real-valued
