<p>This PhD-thesis consists of the five papers</p><p>- On the Hochschild (co)homology of quantum exterior algebras, to appear in Comm. Algebra,</p><p>-Complexity and periodicity, Coll. Math. 104 (2006), no. 2, 169-191,</p><p>-Twisted support varieties,</p><p>-Modules with reducible complexity, to appear in J. Algebra,</p><p>- On support varieties for modules over complete intersections, to appear in Proc. Amer. Math. Soc.</p><p>These papers are roughly divided into two groups; the ¯rst three study modules over Artin algebras using techniques from Hochschild cohomology, whereas the last two papers study modules over commutative Noetherian local rings, in particular modules over complete intersections. </p>
