    dct:description """
              We want to describe the triplets (\\Omega, (g), \\mu) where (g) is the (co)metric associated to some symmetric second order differential operator L defined on the domain \\Omega of R^d and such that L is expandable on a basis of orthogonal polynomials of L_2(\\mu), and \\mu is some admissible measure. Up to affine transformation, we find 11 compact domains in dimension 2, and also give some non--compact cases in this dimension.
