In this paper, n -point quadrature rules associated with a strong distribution � on ( a , b ) , 0 � a < b � ∞ , and exactly integrating certain subspaces of Laurent polynomials with the highest possible dimension are first analyzed. Here the

We consider orderings of nested subspaces of the space of Laurent polynomials on the real line, more general than the balanced orderings associated with the ordered bases {1,z^-^1,z,z^-^2,z^2,...} and {1,z,z^-^1,z^2,z^-^2,...}. We show that with such

Let @f be a c-inversive strong distribution as defined in [A. Sri Ranga, E.X.L. de Andrade, J.H. McCabe, Some consequences of a symmetry in strong distributions, J. Math. Anal. Appl. 193 (1) (1995) 158-168]. In this paper, two-point Pade approximants

Making use of the connection between quadrature formulas on the unit circle and the interval [-1, 1] recently established in [1], explicit expressions for the nodes and the weights of the Gaussian formulas associated with rational modifications of th

In this paper we shall be mainly concerned with sequences of orthogonal Laurent polynomials associated with a class of strong Stieltjes distributions introduced by A.S. Ranga. Algebraic properties of certain quadratures formulae exactly integrating L

Starting from the coefficients of the power expansions for the Dawson's integral both around the origin and infinity, a linear functional acting on the space of Laurent polynomials is defined. In this paper, properties of this functional are studied

Starting from a strong Stieltjes distribution Φ, general sequences of orthogonal Laurent polynomials are introduced and sonic of their most relevant algebraic properties are studied. From this perspective, the connection between certain quadrature f

In this paper the concept of partial Pade approximation is extended to the case of two points, giving a way of construction via two-point Pade and Pade-type approximations. Numerical examples, exhibiting the power of these approximants are also given
