학과 세미나/콜로퀴엄 - 위상수학 세미나: On Translation Lengths of Anosov Maps on Curve Graph of Torus 인쇄
by Changsub Kim(KAIST)
We show that an Anosov map has a geodesic axis on the curve graph of a torus. The direct corollary of our result is the stable translation length of an Anosov map on the curve graph is always a positive integer. As the proof is constructive, we also provide an algorithm to calculate the exact translation length for any given Anosov map.

학과 세미나/콜로퀴엄 - 위상수학 세미나: What is Legendrian? 인쇄
by Youngjin Bae(KIAS)
I will explain the role of Legendrians in the study of symplectic geometry, contact topology, and knot theory. Several Legendrian invariants will be introduced including homotopy type invariants, pseudo-holomorphic curve counting method, and generating families. If time permits, I will also talk about how the Legendrian theory interacts with Lagrangian- and microlocal sheaf theory.
