摘要

In this paper, we consider a type of square functions in difference form, which is a modified one of sharp-edged square functions introduced by Wilson. By adding Lipschitz conditions on the constituent kernels of the square functions, we show that they are bounded on \(L^p(\mathbb {R}^d)\) L p ( R d ) for all \(p\in (1,\infty )\) p ( 1 , ) .
