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