Hardy spaces and Riesz transforms on a Lie group of exponential growth
Peter Sjögren, Maria Vallarino
Let be the Lie group endowed with the Riemannian symmetric space structure. Take a distinguished basis of left-invariant vec…
weights on nonhomogeneous trees equipped with measures of exponential growth
Alessandro Ottazzi, Federico Santagati, Maria Vallarino
This paper aims to study weights in the context of a class of metric measure spaces with exponential volume growth, namely infinite trees with root at infinity equipped with…
Calderón-Zygmund theory on some Lie groups of exponential growth
Filippo De Mari, Matteo Levi, Matteo Monti +1
Let , where is a stratified Lie group and acts on via automorphic dilations. We prove that the group has the Calderón-Zygmund property…
Riesz transform and spectral multipliers for the flow Laplacian on nonhomogeneous trees
Alessio Martini, Federico Santagati, Anita Tabacco +1
Let be a locally finite tree equipped with a flow measure . Let be the flow Laplacian on . We prove that the first order Riesz transform $\nabla \mathcal…
Hardy-Littlewood maximal operators on trees with bounded geometry
Matteo Levi, Stefano Meda, Federico Santagati +1
In this paper we study the boundedness of the centred and the uncentred Hardy--Littlewood maximal operators on the class , , of trees with -bou…
Sharp endpoint results for imaginary powers and Riesz transforms on certain noncompact manifolds
G. Mauceri, S. Meda, M. Vallarino
In this paper we consider a complete connected noncompact Riemannian manifold M with bounded geometry and spectral gap. We prove that the imaginary powers of the Laplacian and the…
