Research Abstract |
Moreover, it follows that Λ is a Frobenius extension over K, and accordingly, we know that the set of integrals of Λ is 1-dimensional over K and any right comodule subalgebra containing Λ is a free module over Λ. l further intend to research whether the proof of the above facts can be obtained without the assumption on the characteristics and X-outerness.
