In this paper we study the analytic torsion and the L2-torsion of compact
locally symmetric manifolds. We consider the analytic torsion with respect to
representations of the fundamental group which are obtained by restriction of
irreducible representations of the group of isometries of the underlying
symmetric space. The main purpose is to study the asymptotic behavior of the
analytic torsion with respect to sequences of representations associated to
rays of highest weights.Comment: 45 pages, references adde
