The conjectures also predict that this basis controls numerics of representations of the Lie algebra of a semi-simple algebraic group over an algebraically closed field of positive characteristic. We check this for almost all characteristics.\n  To this end we construct a non-commutative resolution of the nilpotent cone which is derived equivalent to the Springer resolution.
