Abstract

Let GG be a bounded open subset of Euclidean space with real algebraic boundary Γ\Gamma. Under the assumption that the degree dd of Γ\Gamma is given, and the power moments of the Lebesgue measure on GG are known up to order 3d3d, we describe an algorithmic procedure for obtaining a polynomial vanishing on Γ\Gamma. The particular case of semi-algebraic sets defined by a single polynomial inequality raises an intriguing question related to the finite determinateness of the full moment sequence. The more general case of a measure with density equal to the exponential of a polynomial is treated in parallel. Our approach relies on Stokes theorem and simple Hankel-type matrix identities.
