报告摘要：  

This talk focus on the geometry of grafting rays. We estimate the extremal length of a simple closed curve along the conformal grafting ray determined by any rational lamination. Furthermore, we calculate the endpoint of this conformal grafting ray in the Gardiner-Masur compactified Teichm\uller space. Finally, we obtain a formula of the limit distance of the Teichm\uller metric between these two conformal grafting rays.
