摘要
Orthogonal systems of trigonometric polynomials of semi-integer degree with respect to a weight function w(x) on [0,2 pi) have been considered firstly by Turetzkii in [ A. H. Turetzkii, On quadrature formulae that are exact for trigonometric polynomials, East J. Approx. 11 (2005) 337 - 359 (Translation in English from Uchenye Zapiski, Vypusk 1(149), Seria math. Theory of Functions, Collection of Papers, Izdatel'stvo Belgosuniversiteta imeni V. I. Lenina, Minsk (1959) 31 - 54)]. It is proved that such orthogonal trigonometric polynomials of semi-integer degree satisfy five-term recurrence relation. In this paper we present explicit formulas for five-term recurrence coefficients for some weight functions. (C) 2007 Elsevier Inc. All rights reserved.
