We use a theorem of S. Tolman and J. Weitsman (The cohomology rings of Abelian symplectic quotients, math. DGร9807173) to find explicit formul$ for the rational cohomology rings of the symplectic reduction of flag varieties in C n , or generic coadjoint orbits of SU(n), by (maximal) torus actions. W
## Abstract Let __G__ be a reductive linear algebraic group over an algebraically closed field __K__, let Pฬ be a parabolic subgroup scheme of __G__ containing a Borel subgroup __B__, and let __P__ = Pฬ~red~ โ Pฬ be its reduced part. Then __P__ is reduced, a variety, one of the well known classical
