摘要：In this paper, we completely determine the inequivalent indecomposable modular representations of the dihedral group D-2p in characteristic p > 2 and also consider the structure of F[V] as the D-2p-module. As an application, we study the invariants, Hilbert ideals and coinvariants of D-2p under the low-dimensional representations. Moreover, we also describe the relations between those coinvariants and the regular representation.
