2 × 2 . If H is abelian of order 8, we may use K = k H \* , and if H is abelian of order 4 we use K = kD 8 \* . If H ∼ = D 8 , then in the two possible examples, one has K = kD 8 \* and the other has K = kQ 8 \* . If H ∼ = 2 × 2 × 2 then H has two simple degree 2 characters, χ 1 and χ 2 , and they
For H an infinite dimensional co-Frobenius Hopf algebra over a field k, and A an H-comodule algebra, the smash product A࠻H \* r at is linked to the ring of coinvariants A c o H by a Morita context. We use the Morita setting to show that for co-Frobenius H, equivalent conditions for ArA c o H to be G
