Abstract
In this paper, we study the derivation module of the ring of invariants of k[X,Y ] under the linear action of dihedral groups Dn,q < GL(2,k) mentioned in a paper by Riemenschneider [Die Invarianten der endlichen Untergruppen von GL(2, a), Math. Zeitsch. 153 (1977) 37-50]. We obtained an explicit generating set for the derivation module of R = k[X,Y ]Dn,q. We show that μ(Derk(R)) ≤ O(Dn,q).
