STRONG COMMUTATIVITY PRESERVING GENERALIZED DERIVATIONS ON MULTILINEAR POLYNOMIALS

2019
Let R be a non-commutative prime ring of characteristic different from 2, with right Utumi quotient ring U and extended centroid C and let F and G be generalized derivations of R such that F(x)G(y) - F(y)G(x) = [x, y], for all x, y is an element of S, where S is a subset of R. Here we will discuss the following cases: (a) S = [R, R]; (b) S = L, where L

Sharp maximal estimates for multilinear commutators of multilinear strongly singular Calderón–Zygmund operators and applications

Forum Mathematicum, 2018
Abstract In this paper, we aim to establish the sharp maximal pointwise estimates for the multilinear commutators generated by multilinear strongly singular Calderón–Zygmund operators and BMO functions or Lipschitz functions, respectively.

Boundedness of multilinear commutators of generalized fractional integrals

Mathematische Nachrichten, 2008
AbstractLet L be the infinitesimal generator of an analytic semigroup on L2(ℝn ) with Gaussian kernel bound, and let L–α /2 be the fractional integral of L for 0 < α < n. Suppose that b = (b1, b2, …, bm ) is a finite family of locally integral functions, then the multilinear commutator generated by b and L–α /2 is defined byL–α /2bf = [bm ...

Boundedness for Multilinear Commutators of Littlewood-Paley Operator

2012 Fourth International Conference on Computational and Information Sciences, 2012
In this paper, boundedness for the multilinear commutators of Littlewood-Paley operator is considered. We prove that the multilinear commutators $g_{\psi,\vec{b}}$ generated by Littlewood-Paley operator and Lipschitz function is bounded from $L^{p}({ R}^{n})$ into $\dot{\wedge}_{(\beta-\frac{n}{p})}({ R}^{n})$ and from $L^{\frac{n}{\beta}}({ R}^{n ...

Commuting traces of multilinear maps on invertible elements

Communications in Algebra, 2018
Let R be a unital simple ring. Under some technical restrictions, we characterize m-linear mappings G:Rm→R satisfying [G(u,…,u),u] = 0 for all unit u∈R.

Lipschitz estimates for multilinear commutator of Littlewood-Paley operator

2009
Summary: We study the continuity of multilinear commutators generated by the Littlewood-Paley operator and Lipschitz functions on Triebel-Lizorkin spaces, Hardy spaces and Herz-Hardy spaces.
