Lagrangian intersection of the Gauss images of isoparametric hypersurfaces

Intersection theory of Lagrangian submanifolds plays an important role to study symplectic topology. One efficient tool to study this comes from Lagrangian Floer cohomology, which was first defined by Floer and generalized by Oh. The Floer cohomology ring of a Lagrangian submanifold is independent of the choice of the Hamiltonian isotopy. However, it seems that there are not many non-displaceable examples known by Floer theoretic methods until now.

In this program we will give attention to a very special and nice class of compact embedded Lagrangian submanifolds in complex hyperquadrics, which are obtained as Gauss images of isoparametic hypersurfaces in spheres.

This program aims to meet collaborators to study the Floer cohomogy of Gauss images and their Lagrangian intersection theory.

Welcome to TSIMF

The facilities of TSIMF are built on a 23-acre land surrounded by pristine environment at Phoenix Hill of Phoenix Township. The total square footage of all the facilities is over 29,000 square meter that includes state-of-the-art conference facilities (over 10,000 square meter) to hold many international workshops simultaneously, two libraries, a guest house (over 10,000 square meter) and the associated catering facilities, a large swimming pool, gym and sports court and other recreational facilities.

Mathematical Sciences Center (MSC) of Tsinghua University, assisted by TSIMF's International Advisory Committee and Scientific Committee, will take charge of the academic and administrative operation of TSIMF. The mission of TSIMF is to become a base for scientific innovations, and for nurturing of innovative human resource; through the interaction between leading mathematicians and core research groups in pure mathematics, applied mathematics, statistics, theoretical physics, applied physics, theoretical biology and other relating disciplines, TSIMF will provide a platform for exploring new directions, developing new methods, nurturing mathematical talents, and working to raise the level of mathematical research in China.


Attention Please


Conference booklets, room keys and name badges for all participants will be distributed at the Registry. Please take good care of your name badge. It is also your meal card and entrance ticket for all events. 

Dining Arrangements

All the meals are provided in the Chinese Restaurant (Building B1) according to the time schedule.
