Abstract (English)

We study twisted Reidemeister torsion on graph manifolds and discuss how it can be used to recover the Thurston norm.
Furthermore, we derive an inequality relating the genus function on a circle bundle over an irreducible 3-manifold to the self-intersection number and the Thurston norm.

Translation of the abstract (German)

Wir untersuchen getwistete Reidemeister-Torsion auf Graphenmannigfaltigkeiten und wie man mit Hilfe dieser die Thurston Norm berechnet.
Zusätzlich setzen wir die Komplexitätsfunktion auf einem Kreisbündel über einer irreduziblen 3-Mannigfaltigkeit mit dem Selbstschnitt und der Thurston Norm in Beziehung.
