设r=∑CeK(D2) rc C为二面体群D2的分歧,给出了当ra,rb和rbo均非零时,群代数kD2在Hopf双模kQ1上的模作用以及Hopf代数kD2[kQ1]的结构.
Let D2 be a dihedral group and r = ∑CeK(D2) rc C be a ramification of D2, the kD2-actions on the Hopf bimodule kQ1 and the structure of Hopf algebra kD2[kQ1] are presented for ra, rb and rba being nonzero natural numbers.
