摘要：In this talk, we will show how to prove the strong Arnold chord conjecture for a large family of star-shaped domains in \R^4, which says that for any Legendrian knot on their contact boundaries, there exists a Reeb chord on the Legendrian knot with distinct endpoints. The proof heavily relies on the recent advances in various equivalences of symplectic capacities on monotone toric domains. A higher-dimensional version for star-shaped domains in \R^{2n} also holds under a technical condition. This talk is based on joint work with Jungsoo Kang.
