Representation theory of the Drinfel'd doubles of a family of Hopf algebras

K. Erdmann, E. L. Green, N. Snashall +1

We investigate the Drinfel'd doubles of a certain family of Hopf algebras. We determine their simple modules and their indecomposable projective modules, and we obtain…

The Hochschild cohomology ring modulo nilpotence of a monomial algebra

E. L. Green, N. Snashall, Ø. Solberg

For a finite dimensional monomial algebra over a field we show that the Hochschild cohomology ring of modulo the ideal generated by homogeneous nilpotent elements is a…
