Title:An Introduction to Special Lagrangian Submanifolds and Lagrangian Mean Curvature Flow


Special Lagrangian Submanifolds (Slag) are volume-minimizing submanifolds in Calabi--Yau manifolds, and they are important objects in Mirror Symmetry. However, the general existence theorem for Slags is still unknown. One potential scheme for finding Slags is the Lagrangian Mean Curvature Flow (LMCF), which is the negative gradient flow of the volume functional. In this talk, I will first introduce the basic notions of Slags and LMCF and then describe some recent results.

The Taipei Postdoc Seminar is a weekly seminar that is organized jointly by the Institute of Mathematics of Academia Sinica and the National Center for Theoretical Sciences during the regular academic year. The seminar is held in these two mathematical institutions, with each one of them hosting the event approximately once every two weeks. The National Taiwan University, Academia Sinica, and the NCTS, together employ a significant number of postdoctoral fellows in mathematics from all over the world every year. The diverse scientific and cultural backgrounds of these postdocs create a unique environment of learning, and the goal of the Taipei Postdoc Seminar is to take advantage of this opportunity by bringing together all these postdocs once in a week in an informal-style seminar to enhance discussions and exchange of ideas among the participants. It is our belief that not only will this seminar encourage and eventually lead to more collaboration among mathematicians in Taipei, but it will also give the participants a chance to broaden their own scientific viewpoints. It is our hope that this seminar will greatly enrich the academic experience of the postdoctoral fellows during their stay in Taipei.
