On the asymptotic geometry of nonpositively curved graphmanifolds. (English) Zbl 1031.53059
Summary: We study the Tits geometry of a 3-dimensional graphmanifold of nonpositive curvature. In particular we give an optimal upper bound for the length of nonstandard components of the Tits metric. In the special case of a \(\pi/2\)-metric we determine the whole length spectrum of the nonstandard components.
