Fourier Series and Transforms in Grand Lebesgue Spaces As an particular case - exponential Orlicz spaces (1010.4305v1)

Abstract: In this article we investigate the Fourier series and transforms for the functions defined on the [-pi, pi]^ d or on the R^d and belonging to the (Bilateral) Grand Lebesgue Spaces. As a particular case we obtain some results about Fourier's transform in the so-called exponential Orlicz spaces. We construct also several examples to show the exactness of offered estimations.
