Exists an atlas of Algebraic Groups and also equivalent Coordinate rings?
I was asking yourself if there was a source that detailed well-known algebraic groups and also their equivalent coordinate rings.
Modify: The previous phrasing was dreadful.
Offered an algebraic team $G$, with Borel subgroup $B$ we can create the Flag Variety $G/B$ which is projective. I am wishing for a checklist of the rated ring $R$ such that $Proj(R)$ represents this Flag Variety.
