The Satake isomorphism identi es the irreducible representations of a semisimple algebraic group with the intersection cohomologies of the Schubert varieties in the ane Grassmannian of the Langlands dual group. In the very special case where the Schubert varieties are smooth, one gets an identi cation between the so-called minuscule representations and the cohomology of the so-called minuscule homogeneous spaces. I will explain how this extends to quantum cohomology.
