Estimates for a Rough Fractional Integral Operator and Its Commutators on p-Adic Central Morrey Spaces [PDF]
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 ...

AIMS Mathematics, 2023 In this paper, we establish the boundedness for $ m $th order commutators of $ n- $dimensional fractional Hardy operators and adjoint operators on weighted variable exponent Morrey-Herz space $ \mathrm{M\dot{K}}_{q, p(\cdot)}^{\alpha(\cdot), \lambda ...

Some weighted inequalities for Hausdorff operators and commutators
Journal of Inequalities and Applications, 2018 In this paper, we consider the problem of boundedness of Hausdorff operator on weighted central Morrey spaces. In particular, we obtain sharp bounds for Hausdorff operators on power weighted central Morrey spaces. Analogous results for the commutators of

Bloom weighted bounds for sparse forms associated to commutators [PDF]
Mathematische Zeitschrift, 2023 In this paper we consider bilinear sparse forms intimately related to iterated commutators of a rather general class of operators. We establish Bloom weighted estimates for these forms in the full range of exponents, both in the diagonal and off-diagonal

Compactness Characterizations of Commutators on Ball Banach Function Spaces [PDF]
Potential Analysis, 2021 Let X be a ball Banach function space on ℝ n ${\mathbb R}^{n}$ . Let Ω be a Lipschitz function on the unit sphere of ℝ n ${\mathbb R}^{n}$ , which is homogeneous of degree zero and has mean value zero, and let T _Ω be the convolutional singular integral ...

Modular Commutators in Conformal Field Theory. [PDF]
Physical Review Letters, 2022 The modular commutator is a recently discovered entanglement quantity that quantifies the chirality of the underlying many-body quantum state. In this Letter, we derive a universal expression for the modular commutator in conformal field theories in 1+1 ...

Efficient product formulas for commutators and applications to quantum simulation [PDF]
Physical Review Research, 2021 We construct product formulas for exponentials of commutators and explore their applications. First, we directly construct a third-order product formula with six exponentials by solving polynomial equations obtained using the operator differential method.

On decompositions of matrices into products of commutators of involutions
The Electronic Journal of Linear Algebra, 2022 Let $F$ be a field and let $n$ be a natural number greater than $1$. The aim of this paper is to prove that if $F$ contains at least three elements, then every matrix in the special linear group $\mathrm{SL}_n(F)$ is a product of at most two commutators ...

Commutators in the two scalar and matrix weighted setting [PDF]
Journal of the London Mathematical Society, 2020 In this paper, we approach the two weighted boundedness of commutators via matrix weights. This approach provides both a sufficient and a necessary condition for the two weighted boundedness of commutators with an arbitrary linear operator in terms of ...
