| In this paperwe prove two consequences of the subnormal character of theHessenberg matrixD when the hermitian matrixMof an inner product is a moment matrix. If this inner product is defined by a measure supported on an algebraic curve in the complex plane, then D satisfies the equation of the curve in a noncommutative sense.We also prove an extension of the Krein theorem for discrete measures on the complex plane based on properties of subnormal operators. | |
