报告摘要:
In this study, we investigate the extremal length of simple closed curves and develop a sharp asymptotic estimate for the extremal length of a simple closed curve along a grafting ray determined by a rational lamination. Using the estimation of the extremal length for a rational lamination, we determine the endpoint of the grafting ray on the Gardiner-Masur boundary. Moreover, we derive an explicit formula for the limiting distance between two distinct grafting rays in the Teichm\uller space with the Teichm\uller metric.
