| Feb 5 at 21:53 | comment | added | kindasorta | I believe $Comodf(D)$ should be $Comod(D)$. Many thanks, this totally clarifies everything. Your answer suggest that there is a non-canonical filtration of the $k$-coalgebra of a neutral Tannakian group over $k$. I wonder if this can be used to compute Tannakian fundamental groups. | |
