More precisely, we describe the cohomology by the coordinate ring of a scheme theoretic intersection of a Cartan subalgebra with a certain union of cones of nilpotent elements inside the Lie algebra of the group SL_n. As such, the main result of this note is similar to an earlier description given by de Concini and Procesi.5 pagesAlgebraic GeometryRepresentation Theory20G10, 20B30A new realization of the cohomology of Springer fiberstext
