摘要:

Let L = −△Hn+V be a Schr¨odinger operator on Heisenberg group Hn, 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 Hn. Let T1 = (−△Hn+V )−1V , T2 =(−△Hn+V )−1/2V 1/2, and T3 = (−△Hn+V )−1/2Hn, 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.

关键词: Commutator, BMO, Heisenberg group, boundedness, Riesz transforms as-sociated to Schr¨odinger operators

Note that the kernel of Ti, i = 1, 2, 3 has no smoothness.
