Abstract
Let be an root of unity for and let be the Taft (Hopf) algebra of dimension . In 2001, Susan Montgomery and Hans-J\"urgen Schneider classified all non-trivial -module algebra structures on an -dimensional associative algebra . They further showed that each such module structure extends uniquely to make a module algebra over the Drinfel'd double of . We explore what it is about the Taft algebras that leads to this uniqueness, by examining actions of (the Drinfel'd double of) Hopf algebras "close" to the Taft algebras on finite-dimensional algebras analogous to above. Such Hopf algebras include the Sweedler (Hopf) algebra of dimension 4, bosonizations of quantum linear spaces, and the Frobenius-Lusztig kernel .
