Commutators of the maximal and sharp functions with weighted Lipschitz functions

Pu Zhang, Xiaomeng Zhu

Let $M$ be the Hardy-Littlewood maximal function. Denote by $M_{b}$ and $[b, M]$ the maximal and the nonlinear commutators of $M$ with a function $b$ . The boundedness of $M_{b}$ and $[b…

Monic modules and semi-Gorenstein-projective modules

Pu Zhang

The category $gp (Λ)$ of Gorenstein-projective modules over tensor algebra $Λ = A \otimes_{k} B$ can be described as the monomorphism category $mon (B, gp (A))$ of $B$ ov…

Bi-Frobenius algebra structure on quantum complete intersections

Hai Jin, Pu Zhang

This paper is to look for bi-Frobenius algebra structures on quantum complete intersections. We find a class of comultiplications, such that if $- 1 \in k$ , then a quantum com…

On modules M such that M and M* are semi-Gorenstein-projective

Claus Michael Ringel, Pu Zhang

Let A be an artin algebra. An A-module M is semi-Gorenstein-projective provided that Ext^i(M,A) = 0 for all i > 0. If M is Gorenstein-projective, then both M and its A-dual M* are…

Characterization of Lipschitz Functions via Commutators of Multilinear Singular Integral Operators in Variable Lebesgue Spaces

Jianglong Wu, Pu Zhang

In this paper, the main aim is to consider the boundedness of commutators of multilinear Calderón-Zygmund operators with Lipschitz functions in the context of the variable exponent…
