Hardy--Littlewood maximal operators on certain manifolds with bounded geometry
Stefano Meda, Stefano Pigola, Alberto G. Setti +1
In this paper we study the boundedness of the centred and the uncentred Hardy--Littlewood maximal operators on certain Riemannian manifolds with bounded geometry. Our results…

Triangular maximal operators on locally finite trees
Stefano Meda, Federico Santagati
We introduce the centred and the uncentred triangular maximal operators and , respectively, on any locally finite tree in which each vertex has at least th…
