In this article, the authors study the Lebesgue point of functions from Hajłasz–Sobolev, Besov, and Triebel–Lizorkin spaces with generalized smoothness on doubling metric …
We prove endpoint bounds for derivatives of fractional maximal functions with either smooth convolution kernel or lacunary set of radii in dimensions n≥ 2. We also show that the …
We present a general approach to sparse domination based on single-scale L^ p L p- improving as a key assumption. The results are formulated in the setting of metric spaces of …

This paper studies smoothing properties of the local fractional maximal operator, which is defined in a proper subdomain of the Euclidean space. We prove new pointwise estimates …

We study the behavior of averages for functions defined on finite graphs G, in terms of the Hardy–Littlewood maximal operator M G. We explore the relationship between the geometry …
We study different geometric properties on infinite graphs, related to the weak-type boundedness of the Hardy–Littlewood maximal averaging operator. In particular, we …
In this paper, weighted endpoint estimates for the Hardy–Littlewood maximal function on the infinite rooted-ary tree are provided. Motivated by Naor and Tao, the following Fefferman …
