Necessary cancellation conditions for the boundedness of operators on local Hardy spaces
Galia Dafni, Chun Ho Lau, Tiago Picon +1
In this work we present necessary cancellation conditions for the continuity of linear operators in , , that map atoms into pseudo-molecules. Our nece…
BMO and the John-Nirenberg Inequality on Measure Spaces
Galia Dafni, Ryan Gibara, Andrew Lavigne
We study the space BMO in the general setting of a measure space with a fixed collection of measurable sets of positive and finite measure, consisting of…
Geometric maximal operators and BMO on product bases
Galia Dafni, Ryan Gibara, Hong Yue
We consider the problem of the boundedness of maximal operators on BMO on shapes in . We prove that for bases of shapes with an engulfing property, the corresponding…
BMO on shapes and sharp constants
Galia Dafni, Ryan Gibara
We consider a very general definition of BMO on a domain in , where the mean oscillation is taken with respect to a basis of shapes, i.e. a collection of open sets co…
On the extension of VMO functions
Almaz Butaev, Galia Dafni
We consider functions of vanishing mean oscillation on a bounded domain and prove a analogue of the extension theorem of P. Jones for . We show that if…
Classes of Measures Generated by Capacities
G. Dafni, G. E. Karadzhov, J. Xiao
We introduce classes of measures in the half-space generated by Riesz, or Bessel, or Besov capacities in , and give a geometric characterization…
