Abstract:By using the compositions about the kernel, the boundedness of commutator b, T] is considered which is generated by a BMO(R^n) function b and the singular integral operators T with rough kernel which is defined by
Tf(x)=p.v.∫R^nΩ(x-y)/|x-y|^nf(y)dy
It is proved that b, T] is bounded on Triebel-Lizorkin spaces Fp^α,q(R^n) as Ω∈L(logL)^2(S^n-1).
Keywords:BMO(R~n)  commutator  rough kernel  Triebel-Lizorkin spaces  BMO(Rn)
