Littlewood-Paley square functions and the local Hardy space for Multi-Norm Structures on $R^{d}$

Agnieszka Hejna, Alexander Nagel, Fulvio Ricci

Multi-norm singular integrals and Fourier multipliers were introduced in [29], and one application of these notions was a precise description of the composition of convolution oper…

Schwartz correspondence for real motion groups in low dimensions

Francesca Astengo, Bianca Di Blasio, Fulvio Ricci

For a Gelfand pair $(G, K)$ with $G$ a Lie group of polynomial growth and $K$ a compact subgroup, the "Schwartz correspondence" states that the spherical transform maps the bi- $K$ -i…
