Title in Portuguese
Desigualdades com peso para transformações integrais do tipo de Fourier
Keywords in Portuguese
Desigualdade de Pitt
Desigualdades com peso
Transformação de Hankel
Transformação integral
Transformada de Fourier
Abstract in Portuguese
Neste trabalho, apresentamos o conceito de F-transformação ou transformação integral do tipo de Fourier e exploramos condições necessárias e suficientes para a desigualdade de Pitt. Os resultados são obtidos como consequência das desigualdades do tipo Hausdorff-Young e de resultados do tipo Calderón para as F-transformações. Como aplicação dos resultados, recuperamos a celebrada desigualdade de Pitt para a transformação de Hankel e para a transformada de Fourier de funções radiais.

Weighted norm inequalities
Abstract in English
In this work, we present the concept of F-transform or integral transform of Fouriertype and explore necessary and sufficient conditions for Pitts inequality. The results are obtained as a consequence of Hausdorff-Young type inequalities and Calderón type results for F-transforms. As an application of the results, we recover the celebrated Pitts inequality for the Hankel transform and for the Fourier transform of radial functions.
