Past Talks:Large-scale geometry of the saddle connection graph - Robert TANG, Xi'an Jiaotong-Liverpool University (2022-05-24)For a translation surface, the associated saddle connection graph has saddle connections as vertices, and edges connecting pairs of non-crossing saddle connections. This can be viewed as an induced subgraph of the arc graph of the surface. In this talk, I will discuss bo...
Abstract:we (try to) give a friendly guide for shearing between hyperbolic surfaces in as ``efficient" a manner as possible. On the way, we'll see Teichmueller spaces, Thurston's earthquake theorem, and a novel metric on Teichmueller space called the earthquake metric which has surprising connections to both the Thurston metric and the Weil-Petersson metric. This is work in collaboration with K...
