Popis: | In the paper, the representation rings (or the Green rings) for a family of Hopf algebras of tame type, the 2-rank Taft algebra (at $q=-1$) and its two relatives twisted by 2-cocycles are explicitly described via a representation theoretic analysis. It turns out that the Green rings can serve to detect effectively the twist-equivalent Hopf algebras here. Comment: J. Algebra (to appear), 34 pages (revised the noncommutativity of Green ring of 2-rank Taft algebra \bar A, rewrote the proofs of Jacobson radicals of the three Green algebras, added some remarks and updated references, etc.) |
