We introduce a natural extension of the Riesz potentials to quasimetricmeasure spaces with an upper doubling measure. In particular, theseoperators are defined when the underlying space has components of differingdimensions. We study the behavior of

On approximation of maximal operators

Autor: Aimar, Hugo Alejandro, Carena, Marilina, Iaffei, Bibiana Raquel

We prove that the weak type (1, 1) boundedness of the maximal of a sequence of integral operators on a metric measure space X follows from the uniform weak type on Dirac deltas of the restriction of the operators to a sequence of approximations of X.

Pointwise estimates for gradients of temperatures in terms of maximal functions

Autor: Aimar, Hugo Alejandro, Gomez, Ivana Daniela, Iaffei, Bibiana Raquel

We give a detailed proof, in the case of one space dimension, of a pointwise upper estimate for the space gradient of a temperature. The operators involved are a one-sided maximal Hardy-Littlewood in time and the Calderón sharp maximal operator in s

On the Uniform Doubling of Hutchinson Orbits of Contractive Mappings

Autor: Aimar, Hugo Alejandro, Carena, Marilina, Iaffei, Bibiana Raquel

We are interested in the preservation of doubling properties along the Hutchinson orbit generated by successive applications of contraction mappings on a metric measure space. We construct some elementary examples, built on Muckenhoupt weights, showi
