We consider an infinite Hermitian positive definite matrix M which is the moment matrix associated with a measure with infinite and compact support on the complex plane. We prove that if the polynomials are dense in L2 then the smallest eigenvalue of the truncated matrix Mn of M of size (n + 1) × (n + 1) tends to zero when n tends to infinity. In the case of measures in the closed unit disk we obtain some related results. | |
