Two Weight Commutators on Spaces of Homogeneous Type and Applications
Journal of Geometric Analysis, 2018In 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 ...

Commutators of maximal functions on spaces of homogeneous type and their weighted, local versions
Frontiers of Mathematics in China, 2019We 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 ...

We present a unified method to obtain unweighted and weighted estimates of linear and multilinear commutators with BMO functions, that is amenable to a plethora of operators and functional settings.

We prove some theorems on commutative involutions in a “real” projective geometry in which cobasal homographie ranges may have 0, 1 or 2 self-corresponding points (and therefore a conic and a general line in its plane have 0, 1 or 2 points of intersection).

On the compactness of oscillation and variation of commutators
Banach Journal of Mathematical Analysis, 2019In this paper, we first establish the weighted compactness result for oscillation and variation associated with the truncated commutator of singular integral operators. Moreover, we establish a new CMO(Rn)\documentclass[12pt]{minimal} \usepackage{amsmath}

The Unified Theory for the Necessity of Bounded Commutators and Applications
Journal of Geometric Analysis, 2017This paper gives unified criterions on the necessity of bounded commutators in linear and multilinear settings. Our results relax the restriction of Banach spaces in previous results to quasi-Banach spaces and extend $$BMO(\mathbb {R}^n)$$BMO(Rn) to the ...

Endpoint estimates of linear commutators on Hardy spaces over spaces of homogeneous type
Mathematical methods in the applied sciences, 2018Let (X,d,μ) be a metric measure space of homogeneous type in the sense of Coifman and Weiss. In this article, the authors prove that bilinear operators, which are finite combinations of compositions of commutators and Calderón‐Zygmund operators, are ...

Canadian Journal of Mathematics, 1961
A classical theorem states that if a square matrix B over an algebraically closed field F commutes with all matrices X over F which commute with a matrix A over F, then B must be a polynomial in A with coefficients in F (2). Recently Marcus and Khan (1) generalized this theorem to double commutators.

Commute Replacement and Commute Displacement
Transportation Research Record: Journal of the Transportation Research Board, 2008Working by telecommunication has been the subject of research attention in transportation studies for many years. Particular consideration has been given to occasional working from home (home working) by (full-time, paid) employees who represent a tangible removal of commute trips on days that people work from home.

Sparse and weighted estimates for generalized Hörmander operators and commutators
Monatshefte für Mathematik (Print), 2017In this paper a pointwise sparse domination for generalized Hörmander and also for iterated commutators with those operators is provided generalizing the sparse domination result in Lerner et al. (Adv Math 319:153–181, 2017).
