By applying Pitt’s inequality we prove a weighted L^p version of Gallagher’s inequality for trigonometric series. Furthermore, we consider a family of weights generated by a smoothing process, via convolution operation, whose first steps are the indicator function of a compact interval and the so-called Cesàro weight supported in the same interval. The eventual aim is the comparison of such weights in view of possible refinements of our inequality for p=2.

Abstract
By applying Pitt’s inequality we prove a weighted L^p version of Gallagher’s inequality for trigonometric series. Furthermore, we consider a family of weights generated by a smoothing process, via convolution operation, whose first steps are the indicator function of a compact interval and the so-called Cesàro weight supported in the same interval. The eventual aim is the comparison of such weights in view of possible refinements of our inequality for p=2.File in questo prodotto:
