Coordinate rings and birational charts
Let G be a semisimple simply connected complex algebraic group. Let U be the unipotent radical of a Borel subgroup in G. We describe the coordinate rings of U (resp., G/U, G) in terms of two (resp., four, eight) birational charts introduced by Lusztig [Total positivity in reductive groups, Birkh...
