Pointwise localization and sharp weighted bounds for Rubio de Francia square functions
Francesco Di Plinio, Mikel Flórez-Amatriain, Ioannis Parissis +1
Let be the Fourier restriction of to an interval . If is an arbitrary collection of pairwise disjoint intervals, the square f…
Singular integrals along variable codimension one subspaces
Odysseas Bakas, Francesco Di Plinio, Ioannis Parissis +1
This article deals with maximal operators on formed by taking arbitrary rotations of tensor products of a -dimensional Hörmander--Mihlin multiplier with the iden…
Maximal subspace averages
Francesco Di Plinio, Ioannis Parissis
We study maximal operators associated to singular averages along finite subsets of the Grassmannian of -dimensional subspaces of . The well s…
Rotational smoothing
Pedro Caro, Cristóbal J. Meroño, Ioannis Parissis
Rotational smoothing is a phenomenon consisting in a gain of regularity by means of averaging over rotations. This phenomenon is present in operators that regularize only in certai…
A metric approach to sparse domination
José M. Conde Alonso, Francesco Di Plinio, Ioannis Parissis +1
We present a general approach to sparse domination based on single-scale -improving as a key property. The results are formulated in the setting of metric spaces of homogeneou…
Directional square functions
Natalia Accomazzo, Francesco Di Plinio, Paul Hagelstein +2
Quantitative formulations of Fefferman's counterexample for the ball multiplier are naturally linked to square function estimates for conical and directional multipliers. In this a…
