15 صفحه اولOn a Separation Theorem for the Zeros of the Ultraspherical Polynomials
1. It will be recalled that the ultraspherical polynomials are those which are orthogonal on the interval ( — 1, 1), corresponding to the weight function (1— x2)x~1/2, X>—1/2. In what follows X = 0 will also be excluded. The coefficients of these polynomials are functions of the parameter X appearing in the weight function, and the symbol P„(x, X), indicative of this fact, will be used to denot...
متن کاملA new characterization of ultraspherical polynomials
We characterize the class of ultraspherical polynomials in between all symmetric orthogonal polynomials on [−1, 1] via the special form of the representation of the derivatives pn+1(x) by pk(x), k = 0, ..., n.
متن کاملA Residue Theorem for Malcev-neumann Series
In this paper, we establish a residue theorem for Malcev-Neumann series that requires few constraints, and includes previously known combinatorial residue theorems as special cases. Our residue theorem identifies the residues of two formal series that are related by a change of variables. We obtain simple conditions for when a change of variables is possible, and find that the two related forma...
متن کاملLindstedt Series and Kolmogorov Theorem
the KAM theorem from a combinatorial viewpoint. Lindstedt, Newcomb and Poincaré introduced a remarkable trigonometric series motivated by the analysis of the three body problem, [P]. In modern language, [G2], it is the generating function, that I call Lindstedt series here, ~h(~ ψ) = ∑∞ k=1 ε k~h(k)(~ ψ) of the sequence ~h(k)(~ ψ) of trigonometric polynomials associated with well known combinat...
