Bilinear rough singular integrals under a fractional geometric condition

Binwei Dan, Moyan Qin, Qingying Xue

We establish the Banach-range boundedness of bilinear rough singular integral operators, together with their maximal and maximally truncated forms, under the fractional geometric c…

On the Bounds of Weak $(1, 1)$ Norm of Hardy-Littlewood Maximal Operator with $L lo g L (S^{n - 1})$ Kernels

Moyan Qin, Huoxiong Wu, Qingying Xue

Let $Ω \in L^{1} (S^{n - 1})$ , be a function of homogeneous of degree zero, and $M_{Ω}$ be the Hardy-Littlewood maximal operator associated with $Ω$ defined by $M_Ω(f)(x) = \su…

The limiting weak type behaviors and The lower bound for a new weak $L lo g L$ type norm of strong maximal operators

Moyan Qin, Huoxiong Wu, Qingying Xue

It is well known that the weak ( $1, 1$ ) bounds doesn't hold for the strong maximal operators, but it still enjoys certain weak $L lo g L$ type norm inequality. Let $Φ_n(t)=t(1+(\log^…
