On the uniqueness of multiple trigonometric series

open access: yes, 1958
The multiple trigonometric series ∑ c(m) exp(i(m,x)), where m = (m₁, ... ,m(n)), x = (x₁, …x(n)), (m,x) = m₁^x₁+ ...+ m(n) x(n), and m(j) ≥ 0, is said to be summable (T,k) if the series [symbol omitted] C(p) (x) is summable (C,k) where C(p)(x) denotes ...

Convergence of trigonometric and Walsh-Fourier series

open access: yes, 2016
In this paper we present some results on convergence and summability of one- and multi-dimensional trigonometric and Walsh-Fourier series. The Fej´er and Ces`aro summability methods are investigated.

Rational trigonometric approximations using Fourier series partial sums [PDF]

open access: yes, 1993
A class of approximations (S(sub N,M)) to a periodic function f which uses the ideas of Pade, or rational function, approximations based on the Fourier series representation of f, rather than on the Taylor series representation of f, is introduced and ...

POINTWISE UNIVERSAL CONSISTENCY OF NONPARAMETRIC LINEAR ESTIMATORS [PDF]

open access: yes
This paper presents sufficient conditions for pointwise universal consistency of nonparametric delta estimators. We show the applicability of these conditions for some classes of nonparametric estimators.
