Let the polynomials P n (x), n 1, be defned by P 0 (x)=0, P 1 (x)=1, a n P n+1 (x)+ a n&1 P n&1 (x)+b n P n (x)=xP n (x), n 1. If a n >0 and b n are real then there exists at least one measure of orthogonality for the polynomials P n (x), n=1, 2, ... . The problem of finding conditions on the sequen

β¦ Synopsis
Suppose that m(ΞΎ ) is a trigonometric polynomial with period 1 satisfying m(0) = 1 and |m(ΞΎ
In this paper, we prove a generalization: if m(ΞΎ ) has no zeros in [-1 10 , 1 10 ] and |m( 1 6 )| + m(-1 6 )| > 0, then Ο(x) is an orthogonal function.

Suppose that m(ΞΎ ) is a trigonometric polynomial with period 1 satisfying m(0) = 1 and |m(ΞΎ , is related to the zeros of m(ΞΎ ). In 1995, A. Cohen and R. D. Ryan, "Wavelets and Multiscale Signal Processing," Chapman & Hall, proved that if m(ΞΎ ) has no zeros in [-1 6 , 1 6 ], then Ο(x) is an orthogon
We establish explicit expressions for both P and E in n x a(n)=P(x)+E(x)= ``principal term''+``error term'', when the (complex) arithmetical function a has a generating function of the form `(s) Z(s), where `is the Riemann zeta function, and where Z has a representation as a Dirichlet series having
