L^p BOUNDEDNESS OF COMMUTATOR OPERATOR ASSOCIATED WITH SCHRDINGER OPERATORS ON HEISENBERG GROUP

摘要

Let L=△Hn + V be a Schrdinger operator on Heisenberg group H n,where △Hn is the sublaplacian and the nonnegative potential V belongs to the reverse H¨older class BQ/2,where Q is the homogeneous dimension of H n.Let T1 =(△Hn + V)-1 V,T2 =(△Hn +V)-1/2 V 1/2,and T 3 =(△Hn +V)-1/2 Hn,then we verify that [b,Ti],i = 1,2,3 are bounded on some Lp(Hn),where b ∈ BMO(Hn).Note that the kernel of Ti,i=1,2,3 has no smoothness.
