The Green rings of Taft algebras
We compute the Green ring of the Taft algebra Hn(q), where n is a positive integer greater than 1 and q is an n-th root of unity. It turns out that the Green ring r(Hn(q)) of the Taft algebra Hn(q) is a commutative ring generated by two elements subject to certain relations defined recursively. Conc...

Summary: | We compute the Green ring of the Taft algebra Hn(q), where n is a positive integer greater than 1 and q is an n-th root of unity. It turns out that the Green ring r(Hn(q)) of the Taft algebra Hn(q) is a commutative ring generated by two elements subject to certain relations defined recursively. Concrete examples for n = 2, 3,..., 8 are given. |
