Examples of support varieties for Hopf algebras with noncommutative tensor products Academic Article uri icon

abstract

  • The representations of some Hopf algebras have curious behavior: Nonprojective modules may have projective tensor powers, and the variety of a tensor product of modules may not be contained in the intersection of their varieties. We explain a family of examples of such Hopf algebras and their modules, and classify left, right, and two-sided ideals in their stable module categories. 2014 Springer Basel.
