摘要

．本文的目的是解释一个调和映射的方法，以两个几何问题有关的托雷利图。第一个问题是关于Torelli映射象中完全测地线子流形的存在性，第二个问题是关于映射类群中半简单李群的格表示的刚性。

Torelli Locus and Rigidity

. The goal of the paper is to explain a harmonic map approach to two geometric problems related to the Torelli map. The ﬁrst is related to the existence of totally geodesic submanifolds in the image of the Torelli map, and the second is on rigidity of representation of a lattice of a semi-simple Lie group in a mapping class group.
