Periodic Endomorphisms of Polycyclic Groups

Mediterranean Journal of Mathematics, 2010
Let \(G\) be a polycyclic group. It is a well known fact that any periodic subgroup of \(\Aut(G)\) is finite; on the other hand a semigroup of periodic endomorphisms of \(G\) need not be finite (an element \(\sigma\) of a semigroup \(\Sigma\) is said to be periodic if the semigroup \(\langle\sigma\rangle\) generated by \(\sigma\) is finite; the order ...

ON PERIODIC REPRESENTATIONS OF QUANTUM GROUPS

International Journal of Modern Physics B, 1992
We present some results on representations of quantum groups at the root of unity. In the case of SL(2)q, the classification of the finite dimensional irreducible representations is given. For [Formula: see text] with [Formula: see text] a semi-simple or affine Lie algebra and q an mth root of unity (m odd), we classify the representations of ...
