CODIMENSION OF POLYNOMIAL SUBSPACE IN L2(R, dμ) FOR DISCRETE INDETERMINATE MEASURE μ
نویسندگان
چکیده
A calculation formula is established for the codimension of the polynomial subspace in L2(R, dμ) with discrete indeterminate measure μ. We clarify how much the masspoint of the n-canonical solution of an indeterminate Hamburger moment problem differs from the masspoint of the corresponding N-extremal solution at a given point of the real axis.

Stability of N-extremal Measures
A positive Borel measure μ on R, which possesses all power moments, is N-extremal if the space of all polynomials is dense in L2(μ). If, in addition, μ generates an indeterminate Hamburger moment problem, then it is discrete. It is known that the class of N-extremal measures that generate an indeterminate moment problem is preserved when a finite number of mass points are moved (not “removed”!)...
متن کاملDiscrete Circular Beta Ensembles
Let μ be a measure with support on the unit circle and n ≥ 1, β > 0. The associated circular β ensemble involves a probability distribution of the form P β (μ; t1, t2, ..., tn) = C |V (t1, t2, ..., tn)| β dμ (t1) ...dμ (tn) , where C is a normalization constant, and V (t1, t2, ..., tn) = ∏ 1≤i<j≤n (tj − ti) . We explicitly evaluate the m−point correlation functions when μ is replaced by a discr...
متن کاملMeasures with Finite Index of Determinacy or a Mathematical Model for Dr. Jekyll and Mr. Hyde
In this note measures with finite index of determinacy (i.e. determinate measures μ for which there exists a polynomial p such that |p|2μ is indeterminate) are characterizated in terms of the operator associated to its Jacobi matrix. Using this characterization, we show that such determinate measures with finite index of determinacy (Jekyll) turn out to be indeterminate (Hyde) when considered a...
متن کاملConnection formulas for general discrete Sobolev polynomials: Mehler-Heine asymptotics
In this paper the discrete Sobolev inner product 〈p, q〉 = ∫ p(x)q(x)dμ+ r ∑ i=0 Mi p (c)q(c) is considered, whereμ is a finite positive Borel measure supported on an infinite subset of the real line, c ∈ R and Mi 0, i = 0, 1, . . . , r. Connection formulas for the orthonormal polynomials associated with 〈., .〉 are obtained. As a consequence, for a wide class of measures μ, we give the Mehler–He...
متن کاملRelative Asymptotics for Polynomials Orthogonal with Respect to a Discrete Sobolev Inner Product
We investigate the asymptotic properties of orthogonal polynomials for a class of inner products including the discrete Sobolev inner products 〈h, g〉 = ∫ hg dμ+ ∑m j=1 Nj i=0 Mj,ih (cj)g (cj), where μ is a certain type of complex measure on the real line, and cj are complex numbers in the complement of supp(μ). The Sobolev orthogonal polynomials are compared with the orthogonal polynomials corr...
