Nonnegative trigonometric polynomials
(2002-12-01)
An extremal problem for the coefficients of sine polynomials, which are nonnegative in [0,π] , posed and discussed by Rogosinski and Szego is under consideration. An analog of the Fejér-Riesz representation of nonnegative ...

Spectral properties of temporally aggregated long memory processes
(Escola de Pós-Graduação em Economia da FGV, 2003-10-23)
This paper derives the spectral density function of aggregated long memory processes in light of the aliasing effect. The results are different from previous analyses in the literature and a small simulation exercise ...

Fejér kernel: its associated polynomials
(Boletín de Matemáticas, 2008)
We show that the Fejer kernel generates the fth-kind Chebyshev polynomials.
