A decreasing rearrangement for functions on homogeneous trees
(2005)We introduce a new decreasing rearrangement for functions defined on a homogeneous tree, which enjoys very intuitive and natural properties. The idea is to iterate, with respect to a particular ordering, ... -
Lorentz spaces for decreasing rearrangements of functions on trees
(2004)We characterize the existence of a norm in the Lorentz spaces defined on trees, for non-linear decreasing rearrangements, as well as other functional properties (quasinormability, relationship with ...
