本文系统地研究了粗糙算子的加权跳和变分不等式。更精确地说,我们证明了截断奇异积分族T:={T ε} ε> 0和粗糙核平均算子族M Ω:={M Ω,t} t> 0的一些加权跳跃和变分不等式,它们分别定义为T ε f(x)= ε| y|> ε Ω(y′)|y| n f(x− y)dy和M Ω,t f(x)= 1 t n <$|y| < t Ω(y′)f(x− y)dy,其中核Ω属于L q(Sn − 1),q> 1。
In this paper, we systematically study weighted jump and variational inequalities for rough operators. More precisely, we show some weighted jump and variational inequalities for the families T:={T ε} ε> 0 of truncated singular integrals and M Ω:={M Ω, t} t> 0 of averaging operators with rough kernels, which are defined respectively by T ε f (x)=∫| y|> ε Ω (y′)| y| n f (x− y) d y and M Ω, t f (x)= 1 t n∫| y|< t Ω (y′) f (x− y) d y, where the kernel Ω belongs to L q (S n− 1) for q> 1.
