Fractal and Fractional, 2022 In the current paper, we obtain the boundedness of a rough p-adic fractional integral operator on p-adic central Morrey spaces. Moreover, we establish the λ-central bounded mean oscillations estimate for commutators of a rough p-adic fractional integral ...

Two Weight Commutators on Spaces of Homogeneous Type and Applications [PDF]
Journal of Geometric Analysis, 2018 In this paper, we establish the two weight commutator theorem of Calderón–Zygmund operators in the sense of Coifman–Weiss on spaces of homogeneous type, by studying the weighted Hardy and BMO space for $$A_2$$ A 2 weights and by proving the sparse ...

Fractional integrals and their commutators on martingale Orlicz spaces
, 2020 On the dyadic martingales, Chao and Ombe (1985) proved the L p - L q boundedness of the fractional integrals I α and their commutators [ b , I α ] , where b is in BMO or Lipschitz spaces.

Modified commutators are not sufficient to determine a quantum gravity minimal length scale
Proceedings of 1st Electronic Conference on Universe, 2020 In quantum gravity it is generally thought that a modified commutator of the form [ x ˆ , p ˆ ] = i ħ ( 1 + β p 2 ) is sufficient to give rise to a minimum length scale. We test this assumption and find that different pairs of modified operators can lead

Commutators of maximal functions on spaces of homogeneous type and their weighted, local versions [PDF]
Frontiers of Mathematics in China, 2019 We obtain the characterizations of commutators of several versions of maximal functions on spaces of homogeneous type. In addition, with the aid of interpolation theory, we provide weighted version of the commutator theorems by establishing new ...

MATHEMATICA SCANDINAVICA, 1988 Let \({\mathcal B}\) be a Banach space, \(\sigma\) a \(C_ 0\)-group of isometries of \({\mathcal B}\) with generator \(H\), and \({\mathcal D}\subseteq D(H)\) a \(\sigma\)-invariant core of \(H\). Suppose \(K:{\mathcal D}\to {\mathcal B}\) is a dissipative operator satisfying \[ 1.\quad \| Ka\| \leq k_ 0(\| Ha\| \vee \| a\|),\quad a\in {\mathcal D}, \]

Estimates for the Commutators of p-Adic Hausdorff Operator on Herz-Morrey Spaces
Mathematics, 2019 In this paper, we investigate the boundedness of commutators of matrix Hausdorff operator on the weighted p-adic Herz-Morrey space with the symbol functions in weighted central bounded mean oscillations (BMO) and Lipschitz spaces.
