Fourier Series Acceleration and Hardy-littlewood Series
نویسنده
چکیده
We discuss the effects of the δ2 and Lubkin acceleration methods on the partial sums of Fourier Series. We construct continuous, even Hölder continuous functions, for which these acceleration methods fail to give convergence. The constructed functions include some interesting trigonometric series whose properties were investigated by Hardy and Littlewood.

Marcinkiewicz multiplier theorem and the Sunouchi operator for Ciesielski-Fourier series
Some classical results due to Marcinkiewicz, Littlewood and Paley are proved for the Ciesielski-Fourier series. The Marcinkiewicz multiplier theorem is obtained for Lp spaces and extended to Hardy spaces. The boundedness of the Sunouchi operator on Lp and Hardy spaces is also investigated. 2000 AMS subject classifications: Primary 41A15, 42A45, 42B25, Secondary 42C10, 42B30.
متن کاملDifferentiability and Dimension of Some Fractal Fourier Series
Taking into account that the frequencies of Fourier expansions are integers it is not surprising that some arithmetical results play an important role in many theorems and examples in harmonic analysis. This relation is even clearer from the historical point of view and Hardy and Littlewood can be considered at the same time as founders of a substantial part of harmonic analysis and analytic nu...
متن کاملHardy-littlewood Type Inequalities for Laguerre Series
Let {cj} be a null sequence of bounded variation. We give appreciate smoothness and growth conditions on {cj} to obtain the pointwise convergence as well as Lr -convergence of Laguerre series ∑ cj a j . Then, we prove aHardy-Littlewood type inequality ∫∞ 0 |f(t)|r dt≤ C ∑∞ j=0 |cj| j̄1−r/2 for certain r ≤ 1, where f is the limit function of ∑ cj a j . Moreover, we show that if f(x) ∼ ∑cj a j is ...
متن کاملLattice Points in Cones and Dirichlet Series
Hecke proved the meromorphic continuation of a Dirichlet series associated to the lattice points in a triangle with a real quadratic slope and found the possible poles in terms of the fundamental unit. An analogous result is proven for certain elliptical cones where now the poles are determined by the spectrum of the Laplacian on an arithmetic Riemann surface. 1 Some results of Hardy-Littlewood...
متن کاملThe case of equality in Landau's problem
While investigating summability methods for infinite series [5], Hardy and Littlewood posed an interesting problem which Kolmogorov solved 28 years later and that is the topic for this paper. Write f = O(g) if and only if limx→∞ f (x)/g(x) <∞. Hardy and Littlewood showed that if f is twice continuously differentiable for x > xo and if f = O(1) and f ′′ = O(1), then f ′ =O(1). More generally, th...
