On the module of derivations of rings of invariants of k[X,Y ] under the action of certain dihedral groups
In this paper, we study the derivation module of the ring of invariants of [Formula: see text] under the linear action of dihedral groups [Formula: see text] mentioned in a paper by Riemenschneider [Die Invarianten der endlichen Untergruppen von [Formula: see text], Math. Zeitsch. 153 (1977) 37–50]. We obtained an explicit generating set for the derivation module of [Formula: see text]. We show that [Formula: see text].
