Under a certain finite generation hypothesis, we show that the twisted variety of a module satisfies Dade's Lemma and is one dimensional precisely when the module is periodic with respect to the twisting automorphism. As a special case we obtain results on DTr-periodic modules over Frobenius algebras.22 pages, to appear in J. Pure Appl. AlgebraRings and Algebras16E05, 16E30, 16E40text
