Description:

The Eliashberg-Floer-McDuff theorem is a landmark result in symplectic geometry, stating that any Liouville filling of the standard contact sphere (in dimension at least three) must be diffeomorphic to a ball. This series of lectures will explore this theorem from two perspectives: first, by reviewing the diverse and influential proof techniques it has inspired, and second, by examining its wide-ranging applications—including its unexpected role in solving the smooth rectangular peg problem.

Recent Development around Atiyah Floer Conjecture
AbstractFloer defined Floer homology in two different cases. One is the case of Instanton Floer homology of 3 manifolds (homology sphere). The other uses pseudo-holomorphic curves. (The first Floer homology Floer defined using pseudo-holomorphic curves is Lagrangian Floer homology.) Atiyah-Floer conjecture says that those two coincide in certain situations. This is > 30 year old conjecture. I w...

On arithmetic properties of algebraic curves
课程介绍 / DescriptionIn his memoir of 1900, Henri Poincaré proposed a program to study the arithmetic properties of algebraic curves based on their geometric structures. This led to tremendous achievements in the 20th century, including the proof of the Mordell—Weil theorem (Mordell 1922, Weil 1928), the Mordell conjecture (Faltings 1983), and Fermat's last theorem (Wiles 1994).In this series...
